A chemist needs 225 mL of 2. 4 M HCl. What volume of 12 M HCl must be mixed with water to form this solution?.
nasty-shy [4]

Basedbon dilution formula, the volume of 12 M HCl required is 45 mL.

<h3>What is dilution?</h3>

Dilution is the process of preparing a less concentrated solution from a more concentrated solution.

The dilution formula is as follows:

  • C1V1 = C2V2

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.
