Question

Calculate the mass percent of a sucrose solution that is made by mixing 7.17 grams of sucrose into water until the solution has a mass of 22.7 grams. Give your answer as a whole number. 

______

Answer 1

mass % sucrose = grams sucrose / total grams of solution (x100%)

mass of sucrose = 7.17 grams

total mass of solution = 22.7 grams

mass % of sucrose = 7.17 g / 22.7 g (x100%) = 31.6% rounded to a whole number = 32% sucrose
