The label on an ocean spray cran-rasberry drink lists 30 g of sugar in 240 ml of drink. I weighed 240 ml of drink and found its mass to be 251 g. What is the percent composition of sugar in the drink?

12.0 %.

Explanation:

The percent composition of sugar in the drink = [ (mass of the sugar) / (total mass of the drink) ] x 100.

Mass of the sugar in 240.0 mL of the drink = 30.0 g.

Mass of the 240.0 mL drink = 251.0 g.

∴ The percent composition of sugar in the drink = [ (mass of the sugar) / (total mass of the drink) ] x 100 = [ (30.0 g) / (250.0 g) ] x 100 = 12.0 %
