The volume of 5.1 m H₂O₂ stock solution that should be used to prepare the solution is 9.80 ml.
Dilution is defined as the process in which the concentration of a sample is decreased by adding more solvent. The dilution formula is given below.
C₁V₁ = C₂V₂
where C₁ = initial concentration of sample = 5.1 m
V₁ = initial volume of sample
C₂ = final concentration after dilution = 1.00 m
V₂ = total final volume after dilution = 50.0 ml
Plug in the values to the formula and solve for the volume of the solution needed.
V₁ = C₂V₂/C₁
V₁ = (1.00 m)(50.0 ml)/(5.1 m)
V₁ = 9.80ml
