# If you had 325 grams of a 5.0% by mass solution of citric acid, how many grams would be the acid and how many grams would be water? How many moles of citric acid would it contain?

##### 1 Answer

This solution contains

There is

#### Explanation:

The mass in grams of a mass % solution, is the sum of the mass in grams of the solute and the mass in grams of the solvent. The solute in this question is citric acid, and the solvent is water.

You need to first calculate the mass in grams of citric acid in

Rearrange the mass % equation to isolate grams of solute of citric acid. Insert the known information into the equation and solve.

Now subtract the mass in grams of citric acid from the mass in grams of the solution.

Divide the mass of citric acid by its molar mass by multiplying by its inverse.

The molecular formula for citric acid is
