Answer:
Mass percentage = (Mass of solute/Mass of solution) x 100. Mass percentage of benzene = (15 g/96 g) x 100 = 15.625%. Example – 08: The density of the solution of salt X is 1.15 g mL-1. 20 mL of the solution when completely evaporated gave a residue of 4.6 g of the salt. Calculate the mass percentage of solute in the solution. etc.....
