Performing dilutions

One important consideration when preparing a diluted solution is how much of the stock solution to use, and how much solvent should be added to the stock solution in order to obtain the desired concentration of solute in the diluted solution. To calculate the amount of the stock solution that we need as well as the amount of additional solvent that needs to be added, we use equation (1);

(1) M₁V₁ = M₂V₂

where M₁ and M₂ are the initial and final molarity, respectively, and V₁ and V₂ are the initial and final volume.
