Reed Boyd · Answer 1

The new molarity is 0,96 M.

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

2,4 M x 100ml = C2 x 250 ml

C2 = (2,4 M x 100ml) / 250 ml

C2 = 0,96 M
