Given :

Antonette prepared a solution by dissolving 90 ml of hydrogen peroxide in a given amount of water to make 3000 ml of solution. Identify the concentration of the hydrogen peroxide solution.

To find:

Identify the concentration of the hydrogen peroxide solution.

Solution:

We use the formula, Volume percent = Volume of solute / Volume of solution × 100 %

From given, we have the parameters,  

The volume of solute is 90 mL

The volume of solution is 3000 mL

Substitute the values in the given formula,

Volume percent = Volume of solute / Volume of solution × 100 %

= 90 mL / 3000mL × 100 %

∴ The volume percent = 3 %
