Question

What is the molarity of a solution if you take 1.0L of 2.5 M HCl and dilute it to a total volume of 5.0 L ?

Answer 1

Answer

C2 = 0.50 M

Explanation

Given:

C1 = 2.5 M

V1 = 1.0 L

V2 = 5.0 L

Required: C2- molarity of the solution after dilution

Solution:

The equation to use is:-

C1V1 = C2V2

C2 = (C1V1)/V2

C2 = (2.5 x 1.0)/5.0

C2 = 0.50 M
