The label on a bottle of Hydrogen peroxide reads 3.0% hydrogen peroxide. The bottle is 946 ml. How many ml of hydrogen peroxide does the bottle contain?

28.38 ml of H202

Explanation:

Given data:

the concentration of H2O2  = 3.0 % v/v

it means,

3ml  H2O2 is present in 100 ml of solution.

Therefore, to calculate the amount of H202 in 946 ml bottle of solution, we use the formula:

Percent by volume: volume of solute/volume of solution×100%

we have;

 (3.0 mL/ 100 ml) × 946 mL

= 0.03 x 946 ml

= 28.38ml of H202

it's all four options.
