2.5 cm cube of alcohol is mixed with 75 cm cube of water. Calculate the concentration of the solution.

Given:

Volume of solute = 4.5 cm³ = 4.5 ml

Volume of solvent = 125 cm³ = 125 ml

To find: concentration of the solution

Solutuon:

Volume of solution = Volume of solute  + Volume of solvent

= 4.5 + 125 = 129.5 ml

Concentration = $\frac{Volume \ of \ solute}{Volume \  of \ solution} \times 100$

= $\frac{4.5}{129.5} \times 100$

$= 0.03479 \times 100$

= 3.749%
