Answer:   M  (Molarity )= 0.980  M

            m   (molality )   = 1.10  m

Explanation:  w/w=9.8%,    w (solute)= 9.8g W(solvent)  =  90.2 g   w(solution)=100 g

M  =  w/M.M.                       =  9.8/  98

                               -------------  ×1000             ------------    ×1000   =  0.980  M

                                  V   ( mL)                         100×1.02

    m    =   w/M.M                                9.8  /98

                -----------  ×  1000     =      --------------- ×1000    =  1.10  m

                 W (g)                               ( 100 -  9.8)
