Preform dilution calculations for 10 ml of 2 M stock solution. Molecular weight for the component is 48.6 g / mol
To perform dilution calculations, you need to know the desired final concentration, the volume of the stock solution, and the final volume you want to achieve after dilution.
Let's assume the desired final concentration is C1, the volume of the stock solution is V1, and the final volume you want to achieve is V2.
In this case, the stock solution has a concentration of 2 M and a volume of 10 ml. Let's say we want to dilute it to a final volume of 100 ml.
Now, let's calculate the dilution factor first. The dilution factor (DF) is the ratio of the final volume to the initial volume of the stock solution.
DF = V2 / V1
DF = 100 ml / 10 ml
DF = 10
The dilution factor tells you by how much you need to dilute the stock solution. In this case, the stock solution must be diluted by a factor of 10.
Now, let's calculate the final concentration (C1) after dilution. The final concentration is the initial concentration divided by the dilution factor.
C1 = C0 / DF
C1 = 2 M / 10
C1 = 0.2 M
Therefore, to obtain a final volume of 100 ml with a final concentration of 0.2 M, you need to dilute 10 ml of the 2 M stock solution with 90 ml of a suitable diluent (such as water).
It is important to note that when performing dilutions, you should always double-check your calculations and ensure the accuracy of the concentrations and volumes used.
