When 0.723 L of a 0.89 M solution is diluted to 2.880 L, what is the new molarity

The new molarity is 0,22M

Explanation:

A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).

We use the formula for dilutions:

C1 x V1 = C2 x V2

0,89 M x 0,723L = C2 x 2.880 L

C2 = (0,89 M x 0,723L) / 2.880 L

C2 = 0,22M
