When 0.639 L of a 0.60 M solution is diluted to 2.822 L, what is the new molarity? Report your answer with 4 decimal places.

Liono4ka [1.6K]

Answer:

The new molarity is 0,1359M.

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

0,60 M x 0,639 L= C2 x 2,822 L

C2=(0,60 M x 0,639 L)/ 2, 822 L

C2=0,1359 M
