    Mass per cent of A = mass of A(solute) ÷ mass of solution ×100 Mass of A =20g Mass of solution = mass of A + Mass of solvent ( water) Mass of A = 20 ÷ 20 + 80 × 100 = 20 ÷ 100 × 100 = 20 % .

    Mass percent of solute =  mass of solute​/ mass of solution×100

    Mass of solute = 20 g

    Mass of solvent = 80 g
    Mass of solution = 20 g

    ∴  Mass percent of solute =20/20 ​× 100

    =100%
