Basedbon dilution formula, the volume of 12 M HCl required is 45 mL.
Dilution is the process of preparing a less concentrated solution from a more concentrated solution.
The dilution formula is as follows:
From the given data:
C2 = 2.4 M
V2 = 2.25 mL
C2 = 12 M
V1 = ?
V1 = C2V2/C1
V1 = 2.4 × 225/12
V2 = 45 mL
Therefore, the volume of 12 M HCl required is 45 mL.
