We need to add 7.5 mL of distilled water to the 1% m/V HCI solution available.

What is the volume needed?

The percent concentration is one of the common units of concentration that could be used to describe the amount of substance. Let us now try to obtain the volume needed.

Given that;

C1V1=C2V2

C1 = initial concentration

V1 = Volume of the stock solution

C2 = final concentration

V2 = volume of the new solution

Thus;

V1 = C2V2/C1

V1 = 0.25 * 10/1

= 2.5 mL

Hence, the volume of distilled water needed =  10mL - 2.5 mL

= 7.5 mL

Thus, we need to add 7.5 mL of distilled water to the 1% m/V HCI solution available.
