# To what volume will you have to dilute 30.0 mL of a 12 M HCl solution to make a 0.35 M HCl solution?

## Question:

To what volume will you have to dilute 30.0 mL of a 12 M HCl solution to make a 0.35 M HCl solution?

## Dilutions:

There is a common formula used for calculating dilutions when a more concentrated solution is diluted to a lower concentration solution. That formula is:

$$C_1 \times V_1 = C_2 \times V_2$$

where

C{eq}_1 {/eq} = concentration of the concentrated solution

V{eq}_1 {/eq} = volume of the concentrated solution

C{eq}_2 {/eq} = concentration of the dilute solution

V{eq}_2 {/eq} = volume of the dilute solution

In order for this formula to work, your units for concentration need to match, and your units for volume also need to match.

\rm 12\;M \times 30.0\;mL = 0.35\;M \times...
