# How would you prepare 250mL of a 0.225%(m/v) NaCl solution from a 0.60%(m/v) NaCl stock solution?

## Question:

How would you prepare 250mL of a 0.225%(m/v) NaCl solution from a 0.60%(m/v) NaCl stock solution?

## Concentration of a dilution:

If you are given the desired volume and concentration of a solution, plus the concentration of a stock solution, you use the equation:

$$concentration_1 \times volume_1 =concentration_2 \times volume_2 $$

This will give you the volume of the stock solution that you need. Then you add enough water to reach the desired volume from your problem.
