Question

Calculate the molarity of a solution prepared by diluting 100 mL of 180 M HCl with enough water to make 2500 mL of solution

Answer 1

The molarity of the solution is 7,2 M.

Step-by-step 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
