The volume of stock solution required is 9.3 mL.

What is dilution?

The term dilution refers to the process of adding more solvent to a solution in order to make it less concentrated. In the question, we are told that the stock solution has 30% (w/w) H2O2.

Using the formula;

Co = 10pd/M

Co = concentration of the stock solution

p = percent concentration

d = density of the solution

M = molar mass of the substance

Substituting values;

Co = 10 × 30 × 1.1/34

Co = 9.7 M

Using the dilution formula;

C1V1=C2V2

V1= C2V2/C1

V1 = 3.6 M × 25.00 mL/9.7 M

V1 = 9.3 mL
