Question

To what volume must 1.0 L of a 6.0 M solution of HCl be diluted in order

to prepare a 0.2 M solution? *

Answer 1

30L

Step-by-step explanation:

The following data were obtained from the question:

Volume of stock solution (V1) = 1L

Molarity of stock solution (M1) = 6M

Molarity of diluted solution (M2) = 0.2M

Volume of diluted solution (V2) =..?

The volume of the diluted solution can be obtained as follow:

M1V1 = M2V2

6 x 1 = 0.2 x V2

Divide both side by 0.2

V2 = 6/0.2

V2 = 30L

Therefore, the solution must be diluted to 30L in order to obtain 0.2M of the solution.
