Question

A solution is prepared by dissolving sugar in water. The solution is 25.0%, by mass, sugar. How many grams of WATER are in 472 grams of this solution?

Answer 1

If the sugar makes up 25% of the solution, that means the water makes up 75%, or 3/4, of the solution.

Set up a proportion to solve:

`(3)/(4) = (x)/(472)`

Cross multiply:

`4x = 1416`

`x = 354`

Therefore, there are 354 grams of water in the solution.
