Question

A solution contains 0.3 liters of sulfuric acid. If this represents 12% of the total amount, how do you find the total amount?

Answer 1

The total amount of solution is 2.5 liters. Use a ratio proportion method.

Explanation:

This is more of an algebra problem than a chemistry problem.

0.3 liters = 12%

total volume = 100 %

Set up a ratio proportion.

`0.3/x = 12/100` Solve for x

First multiply both sides by 100 x. This gives

`100 xx x xx( 0.3/x) = 100 xx x xx ( 12/100)` This gives

`100 xx 0.3 = x xx 12` This gives

30 = 12 x divide both sides by 12

`30/12 = 12 x/12` This gives

2.5 = x

x = the total volume of the solutions.
