Answer:

[tex]\sf \fbox {mass \:percentage \: = 9.09 \%}[/tex]

Explanation:

Given:

Mass of solute = 15g

Mass of solvent (Water)= 150g

To find:

Mass percentage of sodium chloride=?

Solution:

Let's find out the mass of overall solution first,

Mass of solution= Mass of solute+ mass of solvent

Mass of solution = 15+150= 165 gram

Now we know that,

[tex] \sf \: mass \:percentage \: = \frac{Mass \: of \: solute}{Mass of solution} \times 100 \\ \sf \: mass \:percentage \: = \frac{15}{165} \times 100 \\ \sf \: mass \:percentage \: = \frac{1500}{165} \\ \sf \fbox {mass \:percentage \: = 9.09 \%}[/tex]
