Thank you You are given 5000 mL of standardized 10 M KOH sol

You are given 500.0 mL of standardized 1.0 M KOH solution. How much volume of this solution is required to prepare 250 mL of 0.75 M KOH solution.

Solution

Molarity of stock KOH solution M₁= 1.0 M

Molarity of standard KOH solution M₂= 0.75 M

Volume of standard KOH solution V₂= 250 ml

M₁V₁= M₂V₂

1 X V₁ = 0.75 X 250

V₁= 187.5 ml of 1 M KOH is required to prepare 250 ml of 0.75 M KOH solution.
