O
a
1.9%
6.5%
.65 %
65%

Answer 1

65%

Step-by-step 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:

`\%\ By \ mass=(Mass \ of \ solute)/(Mass \ of \ solution)* 100\\\\=(255\ g)/(255\ g+135\ g)* 100\\\\=65.38\%\\\\\approx 65\%`

Hence, the mass percent is 65%
