What is your new volume?

Question

You have been given 500mL of a 6 M HCl solution. You add water til the final volume is 1500 mL. What is your new volume?

Answer 1

The new volume is 1500 ml as stated in the problem. What you may be asking is "what is the new concentration of the HCl solution?"

V1M1 = V2M2

(500 ml)(6 M) = (1500 ml)(x M)

x = 2 M
