# 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.

View this answerWe will use the formula {eq}C_1 \times V_1 = C_2 \times V_2 {/eq} to solve this problem:

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