Molarity Dilution Formula

The formula of molarity dilution is:

M1V1 = M2V2

  • M1 = Initial molarity (mol/L)
  • V1 = Initial volume (L)
  • M2 = Final molarity (mol/L)
  • V2 = Final volume (L)

Solved Example

Example – A 2 M solution of hydrochloric acid (HCl), and you want to make 500 mL of a 0.5 M solution, then find the initial volume of the solution.

Solved –

Given, M1 = 2 M, V2 = ? , M2 = 0.5 M, V2 = 500 ml

Put all values into formula = M1V1 = M2V2

V1 = M2V2 / M1 = 0.5 * 500 / 2 = 125 ml

So, the Initial volume (V1) of the solution was 125 ml before diluting
