Question

A solution is prepared by diluting 50.00 mL of 2.575 M solution of HNO3 to 250.00 mL. what is the molarity of the result solution

Answer 1

Given data:

Initial molarity = 2.575 M

Initial volume = 50 mL = 0.05 L

Final volume = 250.00 mL = 0.25L

Asked for

Final molarity.

To find the molarity of the solution after its dilution, we can use the following formula:

(MV)initial = (MV)final

2.575 * 0.05 = M*0.25

M = 0.13/0.25

Mfinal = 0.52 M

The molarity of the resultant solution will be 0.52 M.
