Question

A solution contain 50gm of common salt in 400 gm of water calculate the consentration in term of mass of mass percentage of solution

Answer 1

Mass (solute) = 50 gram

Mass (solvent) = 400 gram

Mass (solution) = Mass (solute) + Mass (solvent)

                        = 50 gram + 400 gram

                        = 450 gram

Mass % (solution) = [ Mass (solute)/Mass (solvent)] × 100

                                = [50/450] × 100

                                = 11.1 %
