The molarity of the solution is 7,2 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

180 M x 100ml = C2 x 2500 ml

C2 = (180 M x 100ml) / 2500 ml

C2 = 7,2M
