Answer:
45.6 millilitres of hydrogen peroxide are in 480.00 mL of 9.5% by volume hydrogen peroxide solution
Step-by-step explanation:
A percentage solution of Hydrogen peroxide is a volume per volume percentage solution. This means that each given percentage solution is expressed as a given mL of the substance found in 100 mL of solution.
A 9.5 percentage hydrogen peroxide solution contains 9.5 mL of hydrogen peroxide in 100 mL of solution.
Millitres of hydrogen peroxide found in 480.00 mL of solution = 9.5/100 × 480 mL = 45.6 mL
Therefore, 45.6 millilitres of hydrogen peroxide are in 480.00 mL of 9.5% by volume hydrogen peroxide solution
