vodka [1.7K]

It's decomposition
A combustion reaction involves carbon dioxide so it can't be that
The water is not being formed
The water is not replaced by the other molecules
So it is decomposition, not just from process of elimination, but also because decomposing water means heating it.

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 g

const2013 [10]

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:
$\frac{3}{4} = \frac{x}{472}$

Cross multiply:
$4x = 1416$
$x = 354$

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