A known mass W B of the non-volatile solute is dissolved in a known mass (W A ) of the volatile solvent to prepare a dilute solution and relative lowering of vapor pressure is determined experimentally. Knowing the molecular mass (M A ) of the solvent, molecular mass (M B ) of the solut..

From this experiment, we can conclude that when the center of gravity is nearer the base of support as in figure (b) above, the body is in the stable equilibrium. In figure (a) in previous experiment and figure (a) above, the body is said to be in unstable equilibrium. The body is said to be in ne..
