A student finds a rock on the way to school. In the laboratory he determines that the volume of the rock by placing the rock in a graduated cylinder with 50 mL of water and watched the water rise to 72.7 mL. The student determined the mass is 39.943 g through the use of a triple beam balance. What is the density of the rock?

Answers

Answer:

1.76 g/mL

Explanation:

You need to find the volume. You can do this by subtracting the volume of the water and the rock by the volume of the water.

72.7 mL - 50 mL = 22.7 mL

Now that you have volume, divide the mass by the volume to find the density.

39.943 g/22.7 mL = 1.76 g/mL

The atomic radius of magnesium is 150 pm. The atomic radius of strontium is 200 pm. What is the atomic radius of calcium

Answers

Answer:

The atomic radius of calcium is approximately 175

Explanation:

Given that the atomic radius of magnesium = 150 pm

The atomic radius of strontium = 200 pm

Therefore, given that calcium comes in between magnesium and strontium in group 2 of the periodic table, the atomic radius should be half way between the length of the atomic radius of magnesium and strontium, given that the atomic radius is not a fixed quantity

Therefore;

The atomic radius of calcium is approximately given as follows;

The approximate atomic radius (200 + 150)/2 = 175 pm.

Is neon transparent translucent or opaque

Answers

It would be opaque because transparent is you can see through it clearly translucent is you can see through it but it’s not completely clear and opaque is you can not see through it at all. Hope it help

Neon is transparent opaque as it is light, colorless and order less inert noble gas.

What are noble gas?

Noble gas are defined as the element that belong to group 18 of the modern periodic table.

It is also known as inert gas or aerogene.

Noble gas are light, transparent, colorless and order less gases.

They are the group of six inert or non reactive gases.

Noble gases are odorless, colorless, nonflammable gases with negligible chemical reactivity.

Noble gases are exceedingly stable and unlikely to form chemical bonds due to their complete valence electron shells, which have no tendency to add or lose electrons.

Noble gas were originally classified as group 0 in the periodic table because it was thought they had a valence of zero, which means their atoms could not mix with those of other elements to form compounds.

Thus, Neon is transparent opaque as it is light, colorless and order less inert noble gas.

A cube of aluminum has a mass of 500g. What will be the mass of a cube of magnesium of the same dimensions?
(Density of aluminum is 2.7g/ml)

Answers

The mass of a cube of magnesium : 322.2 g

Further explanation

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

The unit of density can be expressed in g / cm³ or kg / m³

Density formula:

[tex]\large{\boxed {\bold {\rho~=~ \frac {m} {V}}}}[/tex]

ρ = density , g / ml

m = mass , g

v = volume , ml

mass of aluminum = 500 g

density of aluminium = 2.7 g/ml

there is data that needs to be added⇒ density of magnesium : 1.74 g/ml

the same dimensions = the same volume

volume of aluminum

[tex]\tt V=\dfrac{m}{\rho}\\\\V=\dfrac{500}{2.7}=185.19~ml[/tex]

mass of magnesium

V magnesium = V aluminum

[tex]\tt m=\rho\times V\\\\m=1.74\times 185.19\\\\m=\boxed{\bold{322.2~g}}[/tex]

The cube of same dimensions of magnesium and aluminum have same volume. The mass of cube of magnesium has been 321.85 grams.

What is density?

The density has been given as the mass of substance per unit volume. The density of aluminum cube has mass 500 grams, and density 2.7 g/mL. The volume of the aluminum cube has been:

[tex]\rm Density=\dfrac{Mass}{Volume}\\\\2.7\;g/mL=\dfrac{500\;g}{Volume} \\\\Volume=185.18\;mL[/tex]

The volume of the magnesium and aluminum cube has been the same. The density of magnesium has been 1.735 g/mL. Thus, the mass of Mg cube has been given as:

[tex]\rm 1.738\;g/mL=\dfrac{Mass}{185.18\;mL}\\\\ Mass=321.85\;g[/tex]

Thus, the mass of magnesium cube has been 321.85 grams.

A mechanical pencil has a mass of 47.4 grams. The volume of the pencil is 15.8 cubic centimeters. What is the density of the pencil?

Answers

density = mass over volume
so
47.4g/15.8cm^3
=3g/cm^3

Answer:

3 g/cm^3

Explanation:

Density can be determined by mass divided by volume, or P=m/V.

This would be 47.4 grams (mass) / 15.8 cubic centimeters (volume). The units are grams per cubic centimeter, noted as g/cm^3.

cubic centimeter (cm^3) has the same volume as a

Answers

Answer:

1 cc=1 ml=0.001 liter

Explanation:

One cubic centimeter has the same volume as one milliliters. Both are equally used in analytical problems to express the volume of a substance.

What is volume ?

Volume is a physical quantity that measures the total space occupied by a substance. Volume is an extensive quantity and thus depends on the amount of the substance.

The mass of a substance per unit volume is called its density. Volume is dependent on the intermolecular forces between the particles of the substance. The SI unit of volume is liter (L). Other units are ml, cm³, dm³ etc.

One cubic centimeter has the volume as one milliliters.

Hence, 1 cm³ = 1 ml

1000 m or 1000 cm³ is one liter of the substance.
