Answer:
% m/m (sugar) = 7.77 %
Explanation:
Step 1: Given data
Mass of sugar (solute): 17.5 g
Mass of solution: 225 g
Step 2: Calculate the percent by mass of sugar
The percent by mass of sugar is equal to the mass of sugar divided by the mass of the solution times 100%.
% m/m (sugar) = (mass of sugar / mass of solution) × 100%
% m/m (sugar) = (17.5 g / 225 g) × 100%
% m/m (sugar) = 7.77 %
