Question

What is the percent by mass of solute if 14.60g 74.95g of water?​

Answer 1

Answer:

16.30 %

Explanation:

• The percent by mass is calculated by dividing the mass of solute by the mass of solution and then multiplying by 100.
• That is. Percent by mass = (Mass of solute/Mass of solution) × 100

In this case;

Mass of solute = 14.60 g

Mass of solvent = 74.95 g

But, Mass of solution = mass of solute + mass of solvent

Thus;

Mass of solution = 14.60 g + 74.95 g

                           = 89.55 g

Therefore;

% mass = (14.60 ÷ 89.55 g) × 100%

            = 16.30 %

Hence, the mass percent is 16.30%
