When 0.50 L of a 12 M solution is diluted to 1.0 L, what is the resulting molarity?

The resulting molarity is 6M.

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

12 M x 0,5L = C2 x 1,0 L

C2 = (12 M x 0,5 L) / 1,0 L

C2 = 6 M
