Define and explain molar mass.

Define and explain the standard enthalpy of vapourisation (Molar enthalpy of vapourisation).

Define molar conductivity of a solution and explain how molar conductivity changes with change in concentration of a solution for a weak and a strong electrolyte.

Explain why the solubility of amines in water decrease on increasing molar mass.

Define molality and molarity . Why is molality preffered over molarity?

Define molality, molarity.

Define the explain the standard enthalpy of fusion (Molar enthalpy of fusion).

Explain depression in freezing point. How depression in freezing point can be used to find molar mass of a non-volatile solute? Define molal depression constant.
