Question

a chemist needs 225 ml of 2.4 M HCl. what volume of 12 M HCl must be dissolved in water to form this solution?

Answer 1

Hey

Answer 2

The formula used here is M1V1 = M2V2

M1 & M2 are molarities of different sol.
V1 & V2 are volume of different sol.

So,
225 * 2.4 = V2 12.0

=> 225 * 2.4
... .------------- = V2. Here V2 = final volume required to dissolve it.
... ..12.0

Thus 45 mL of water is the final volume, required. @alisha157
