# If 30.0 mL of 12.0 M HCl stock solution are diluted to a volume of 500 mL, what is the molarity of the dilute solution?

Apr 7, 2016

0.72 M

#### Explanation:

$$Required conc. = ml * stock conc. / make up vol.


So, we can apply the calculation

$$                          = 30 * 12 / 500
= 0.72 M
