The volume of the concentrated solution required to prepare 100 mL of a 0.40 mol/L solution of copper (II) sulfate from a 1.80 mol/L solution is 22.22mL.
How to calculate volume?
Volume is a three-dimensional measure of space that comprises a length, a width and a height.
It can be measured in units of cubic centimeters (cm³), cubic inches (in³), however, that of a solution is measured in litres or milliliters (mL).
The volume of a solution can be calculated using the following formula:
C1V1 = C2V2
Where;
- C1 = initial concentration
- C2 = final concentration
- V1 = initial volume
- V2 = final volume
100 × 0.4 = 1.8 × V2
40 = 1.8V2
V2 = 40 ÷ 1.8
V2 = 22.22mL
Therefore, the volume of the concentrated solution required to prepare 100 mL of a 0.40 mol/L solution of copper (II) sulfate from a 1.80 mol/L solution is 22.22mL.
