Answer to Question #141577 in General Chemistry for yara
Question #141577
A solution is made by adding 25mL of benzene to the solvent toluene. The volume of the solution is 80mL. What is the percent concertation by volume of benzene?
Expert's answer
Volume of benzene (solute) = 25mL
Volume of solution = 80mL
% volume conc. = volume of solute/volume of solution × 100%
% volume conc. = 25/80 × 100%
% volume conc. = 31.25%
The %concentration by volume of benzene in toluene is therefore 31.25%.
