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?


Sagot :

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:
[tex] \frac{3}{4} = \frac{x}{472}[/tex]

Cross multiply:
[tex]4x = 1416[/tex]
[tex]x = 354[/tex]

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