Answer:
23.81%
Explanation:
The mass percent of a solution, also known as percentage by weight or w/w%, can be calculated using the formula:
mass percent = (mass of solute / mass of solution) x 100%
In this question;
Mass of solute (sugar) = 15g
Mass of solution (sugar + water) = 63g
Hence,
w/w% = 15/63 × 100
w/w% = 0.2381 × 100
w/w% = 23.81%
Therefore, the mass percent of the sugar solution is 23.81%.
