A solution contains 5.6 mL of alcohol mixed with 75 ml of water. Calculate the concentration of this solution.
Volume of the solute (salt) = 5.6 ml
Volume of the solvent (water) = 75 ml
Volume of the solution = Volume of the solute + volume of the solvent
= 5.6 + 75 = 80.6ml
Volume percentage of solution = Volume of solute /Volume of solvent x 100%
= 5.6/80.6 x 100 = 6.9%
