Mass (solute) = 40 gram
Mass (solvent) = 320 gram
Mass (solution) = Mass (solute) + Mass (solvent)
                         = 40 gram + 320 gram
                         = 360 gram
∴ Mass % (solution) = [ Mass (solute)/Mass (solvent)] × 100
                                 = [40/360] × 100
                                 = 11.1 %
