Answer:

65%

Explanation:

-Given the mass of the solute, sugar is 255 g and of the solvent, water is 135g.

-We apply the percent by mass formula as below:

[tex]\%\ By \ mass=\frac{Mass \ of \ solute}{Mass \ of \ solution}\times 100\\\\=\frac{255\ g}{255\ g+135\ g}\times 100\\\\=65.38\%\\\\\approx 65\%[/tex]

Hence, the mass percent is 65%
