A solution contains 50g of common salt in 400g of water. Calculate the concentration in terms of mass by mass percentage of the solution.
11.11%
Mass of solute = 50g
Mass of solvent = 400g
Mass of solution = Mass of solute + mass of solvent = 50 + 400 = 450g
Mass percentage of solution = mass of solutemass of solution×100 = 50450×100 = 11.11%
