Molarity Dilution Calculator – Enter any three input fields then click the calculate button you get the remaining value, and you can calculate M1, V1, M2, and the final volume.
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
