Question

What is the concentration (in mol / dm3) of KCl in the solution formed by mixing 25 mL of KCl solution, 0.100 M concentration with 50 mL of KCl solution, 0.100 M concentration?

Answer 1

The concentration of both solutions is equal. Therefore, we will get 75 ml of 0.100 M KCl solution.

0.100 M = 0.100 mol/dm³.
