Answers

Answer 1

Answer:

I think the w/w% of this question is 10.

Answer 2

The w/w% of a solution that contains 10 grams of solute and 100 grams of solvent is 9.09%

What is mass percentage % ?

Mass percentage is another name of w/w % or weight /weight % .

To determine the weight/weight % of a solution :

we divide the mass of solute by mass of the solution (solute and solvent together) and multiply by 100 to obtain per cent.

[tex]\dfrac{w}{w} \; \%\; =\;\rm\dfrac{mass \;of\; solute}{mass\; of \; solute\;+\;mass\;of\;solvent} \times 100[/tex]

It is given that , mass of solute = 10 grams and mass of solvent = 100 grams

So,

[tex]\dfrac{w}{w} \; \%\; =\;\rm\dfrac{10}{10+100} \times 100[/tex]

[tex]\dfrac{w}{w} \; \%\; =\;\rm\dfrac{10}{110} \times 100\\\\\dfrac{w}{w} \; \%\; =\;\rm\dfrac{100}{11}\\\\\dfrac{w}{w} \; \%\; =\; 9.09 \;\%[/tex]

The w/w% of a solution that contains 10 grams of solute and 100 grams of solvent is 9.09% .
