What is the mass of sugar and water that will be required to prepare an 800 g solution with a 15% sugar mass fraction?

The total mass of this solution will be 800 grams.

15% of this mass will be sugar, and 85% of this mass will be water.

Find the mass of water and sugar by multiplying the mass of the solution by the mass fraction:

m sugar = 800 x 0.15 = 120 grams;

m of water = 800 x 0.85 = 680 grams;

Verification:

120 + 680 = 800 grams;
