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

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%
