## Introductory Chemistry (5th Edition)

Here we need to calculate the mass percent of sugar. Mass % is given by $=$ (Mass of Solute)$\times$ 100/ (Mass of Solution) Here, the mass of solute (sugar)= 42g Mass of solvent (water)= 311g Mass of solution (solute + solvent) = 353g Therefore Mass Percent of sugar $=$ $\frac{42 \times 100}{353}$ $=$ 11.89%
