    Mass of solute=40g ". ". Solvent= 320g Mass of solution= mass of solute+ mass of solvent 40+320 = 360 Mass by mass formula= Mass of solute × 100 = Mass of solvent 40 x 100 = 4 × 100 now do it by your self 360. 36

    Mass of solute = 40g

    Mass of solvent = 320g

    Mass of solution = Mass of solute + Mass of solvent                     
    = 40g + 320g                     
    = 360gMass percentage of solution = (Mass of solute/Mass of solution)x100
     =   40 / 360  x  100

     = 11.1%
