Answer:

736 mmHg = 0.97 atm (Approx.)

736 mmHg = 736 Torr

Explanation:

Given barometer in the laboratory atmospheric pressure data:

Atmospheric pressure in mmHg = 736 mmHg

Find:

Change given data into Torr

Change given data in atm (atmospheric pressure)

Computation:

We know that;

1 atm = 760 mmHg

So,

736 mmHg = 736 / 760

736 mmHg = 0.97 atm (Approx.)

We know that;

760 mmHg = 760 Torr

So,

736 mmHg = 736 Torr

Given :

A sample of methane gas (CH₄) with a mass of 58 g is kept in a 1.5 L container at a temperature of 373 K.

To Find :

The pressure of the gas.

Solution :

Moles of methane :

[tex]n = \dfrac{58\ gram}{16\ gram/mol} \\\\n = 3.625\ moles[/tex]

We know, by ideal gas equation :

PV = nRT

Here, R is ideal gas equation, [tex]R = 0.082 \ L \ atm\ mol^{-1} \ K^{-1}[/tex]

So,

[tex]P = \dfrac{nRT}{V}\\\\P = \dfrac{3.625\times 0.082 \times 373}{1.5}\ atm\\\\P = 73.92 \ atm[/tex]

Hence, this is the required solution.

Answer: The molarity of given solution is 8.26 M.

Explanation:

Given: No. of moles = 6.2 mol

Volume = 750 mL (1 mL = 0.001 L) = 0.75 L

Molarity is the number of moles of a substance present in a liter of solution.

Therefore, molarity of given solution is converted as follows.

[tex]Molarity = \frac{no. of moles}{Volume (in L)}\\= \frac{6.2 mol}{0.75 L}\\= 8.26 M[/tex]

Thus, we can conclude that the molarity of given solution is 8.26 M.

The answer is D

Explanation:

Answer:56%

Explanation:

In the dewpoint chart when you line it up it ends up at 56%

The relative humidity of the air when the dry temperature is about 4 degrees and the dew point is about -4 degrees C is 56%. Hence option  4 is correct.

The dew point is the temperature at which the air needs to be colled at a ta constant pressure in order to have an RH of 100%. The dew point is minus four degrees and the RH of the air is 4 degrees.

For the forces to initiate the air must get cooler and a constant addition of water pressure should be there. Thus substrating the temperature of the wet bulb, putting the thermometer on the dry bulb, and making use of the RH chart tells us that RH is 56%

Answer:

Isotopes

Explanation:

iso means the same like in triangles (isosceles) so the atoms are the same element but different in mass. Since the isotopes have the same number of protons and electrons the isotopes have much the same chemical behavior. Since the isotopes have different numbers of neutrons the nuclear behavior differs.

Answer:

31.25

Explanation:

The half life is 5.3 years

This means that 1.2 of the orginal matter is left after every 5.3 years.

To find this, divide 26.5(total years) by 5.3(hald life)

This gets you 5.

This is how many times half life occurs, or how many times the total mass is split in half.

This can be though of 1/2^5th power

Hello there!

In this case, according to the definition of the Boyle's law, which describes de pressure-volume behavior as an inversely proportional relationship, it is possible for us to write:

[tex]P_1V_1=P_2V_2[/tex]

Thus, since we are given the initial pressure and temperature, and the final pressure, we are able to calculate the final volume as shown below:

[tex]baV_2=\frac{P_1V_1}{P_2}\\\\V_2=\frac{8.0L*1.013bar}{ 0.968bar}\\\\V_2=8.4L[/tex]

Explanation:

He used just the right amount of matter in water to get it to evaporate at a normal temperature and to condense into clouds for rain.

To cause water evaporate at a regular temperature and condense in clouds for rain, God has employed precisely the proper amount of substance in the water.

Water is constantly circulated throughout the Earth-atmosphere system throughout the water cycle, also known as the hydrologic cycle. The five key stages of the water cycle—evaporation, transpiration, condensate, precipitation, and runoff—are the most crucial. Water is used by all of the processes in the cycle, but its distribution changes over time even while the overall amount of water is largely constant.

Water is converted from its liquid state to its gaseous, or smoke, state through evaporation. This transfer happens when some water molecules have accumulated enough kinetic energy to launch themselves off the water's surface. To cause water evaporate at a regular temperature and condense in clouds for rain, God has employed precisely the proper amount of substance in the water.

Therefore, to cause water evaporate at a regular temperature and condense in clouds for rain, God has employed precisely the proper amount of substance in the water.

Explanation:

Solution :

According to Henry's law of solubility, we have c = kp

Henry's law constant, [tex]$k=\frac{c}{p}$[/tex]

                                      [tex]$=\frac{0.00056}{0.80}$[/tex]

                                      = 0.0007 mol/L.atm

When the pressure is = 4 atm

The solubility is c = 0.0007 mol/(L.atm) x 4 atm

                             = 0.0028 mol/L

Therefore, in a 5 liter of blood, the moles of nitrogen dissolved

= 0.0028 x 5

= 0.014 moles

At the surface, the solubility is = 0.00056 mol/L

So the moles of the nitrogen dissolved = 5 x 0.00056

                                                                  = 0.0028 moles

Therefore, the number of moles of nitrogen released = 0.014 - 0.0028

                                                                                         = 0.0112 moles

Given total pressure = 1 atm                                                                        

Temperature = 37 degree C

                     = 37 + 273

                      = 310 K

R = [tex]$0.0821\ L -atm/ mol.K $[/tex]

Therefore, volume of the nitrogen is

[tex]$V=\frac{nRT}{P}$[/tex]

[tex]$V=\frac{0.0112 \times 0.0821 \times 310}{1}$[/tex]

  = 0.285 L

Answer:

2.09 atm

Explanation:

Step 1: Given and required data

We won't need the data of water and uncombusted fuel, since the partial pressures are independent of each other.

Step 2: Calculate the number of moles (n) corresponding to 60.0 g of CO₂

The molar mass of CO₂ is 44.01 g/mol.

60.0 g × 1 mol/44.01 g = 1.36 mol

Step 3: Calculate the partial pressure of CO₂

We will use the ideal gas equation.

P × V = n × R × T

P = n × R × T/ V

P = 1.36 mol × (0.0821 atm.L/mol.K) × 468.2 K/ 25.0 L = 2.09 atm

The partial pressure of [tex]\rm CO_2[/tex] in 25 L fuel combustion vessel has been 2.09 atm.

From the ideal gas equation:

PV =nRT

P= partial pressure

V = volume = 25 L

n = moles of carbon dioxide

Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]

Moles of [tex]\rm CO_2[/tex] = [tex]\rm \dfrac{60}{44}[/tex] mol

Moles of [tex]\rm CO_2[/tex] = 1.36 mol

R = constant = 0.0821 atm.L/mol.K

T = temperature in Kelvin =  468.2 K

Partial pressure of [tex]\rm CO_2[/tex] = [tex]\rm \dfrac{1.36\;\times\0.0821\;\times\;468.2}{25}[/tex]

Partial pressure of [tex]\rm CO_2[/tex] = 2.09 atm.

The partial pressure of [tex]\rm CO_2[/tex] in 25 L fuel combustion vessel has been 2.09 atm.

Answer:

2.39 atm

Explanation:

We'll begin by calculating the number of mole in 0.41 g of neon (Ne). This can be obtained as follow:

Mass of Ne = 0.41 g

Molar mass of Ne = 20 g/mol

Mole of Ne =.?

Mole = mass / molar mass

Mole of Ne = 0.41 / 20

Mole of Ne = 0.0205 mole

Next we shall convert 200 mL to L.

1000 mL = 1 L

Therefore,

200 mL = 200 mL × 1 L / 1000 mL

200 mL = 0.2 L

Next, we shall convert 11 °C to Kelvin temperature.

T(K) = T(°C) + 273

T(°C) = 11 °C

T(K) = 11 + 273

T (K) = 284 K

Finally, we shall determine the pressure. This can be obtained as follow:

Mole of Ne (n) = 0.0205 mole

Volume (V) = 0.2 L

Temperature (T) = 284 K

Gas constant (R) = 0.0821 atm.L/Kmol

Pressure (P) =?

PV = nRT

P × 0.2 = 0.0205 × 0.0821 × 284

P × 0.2 = 0.4779862

Divide both side by 0.2

P = 0.4779862 / 0.2

P = 2.49 atm

Therefore, the pressure of the gas is 2.39 atm
