Prepare 100 ml solution with a concentration of 0.01 M hydrochloric acid (HCl) using 1.0 M stock solution.

General information:
In dilution problems, the number of moles (concentration × volume) does not change. Therefore, the following equation can be used:


C1 × V1 = C2 × V2

Where, C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, V2 is the final volume.
In this problem, we need to find the volume of the stock solution required to make the dilution.

Calculations:

1.0 M × V1 = 0.01 M × 100 ml

V1 = 1.0 ml

We need to take 1.0 ml from the stock solution and place it in a 100 ml volumetric flask. The volume is completed to the 100 ml mark with freshly distilled water.
