Answer» Answer: The ELEVATION in the BOILING point is given by the expression ΔT b =K b ⋅m.....(1) The molality is given by the expression m= M 2 ⋅W 1
W 2
......(2) Substitute EQUATION (2) in equation (1) ΔT b =K b ⋅ M 2 ⋅W 1
W 2
Hence, the expression for the molar mass of the solute is M 2 = ΔT b ⋅W 1
K b ⋅W 2
