How many mL of a 2.0 M CuCl2 solution are needed to make 500 mL of a 0.5 M solution?

There is 125 mL of a 2.0 M CuCl2 solution are needed to make 500 mL of a 0.5 M solution

Explanation:

Given: = 2.0 M,       = ?

= 0.5 M,       = 500 mL

Formula used to calculate the volume is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that there is 125 mL of a 2.0 M solution are needed to make 500 mL of a 0.5 M solution.
