An emptybottle of capacity 50ml weighs 27g.When completely filled with glycerine,it weighs 92g .calculate the density of glycerine .express your answer in S.I. unit?

Expert Answer
Mass of the bottle = 27 g = 0.027 kg
Mass of bottle + mass of glycerine = 92 g = 0.092 kg
Thus,
mass of glycerine = 0.092 - 0.027 = 0.065 kg
Capacity of bottle = Volume of liquid = 50 ml = 5 x 10-5 m3
Thus, denisty of glycerine = m/V = 0.065/(5 x 10-5) = 1300 kg/m3
