What volume of 10 M HCl must be used to create 100 mL of a 5 M solution.

A volume of 50 mL of 10 M HCl must be used to create 100 mL of a 5 M solution.

Explanation:

Given: = ?,           = 10 M

= 100 mL,             = 5 M

Formula used to calculate the volume is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that a volume of 50 mL of 10 M HCl must be used to create 100 mL of a 5 M solution.
