Answer
Mass percentage of sugar = 34.9%
Explanation
Given:
Mass of sugar (solute) = 471 g
Mass of solution (solute + solvent) = 877 + 471g = 1348 g
Required: mass percentage of sugar
Solution
Percent by mass is the mass of the solute divided by the mass of the solution, multiplied by 100.
[tex]\%\text{ by mass = }\frac{mass\text{ of solute}}{mass\text{ of solution}}\text{ x 100}[/tex][tex]\begin{gathered} \%\text{ by mass of sugar = }\frac{471\text{ g}}{877\text{ + 471 g}}\text{ x 100} \\ \%\text{ by mass of sugar = }\frac{471}{1348}\text{ x 100} \\ \\ \%\text{ by mass of sugar = 34.9}\% \end{gathered}[/tex]
