The molality of the solution is______ m.
The boiling point of the solution is_______ Celsius.
Given : boiling point of pure solvent i.e diethyl ether = 34.50 oC
Mass of solute i.e chlorophyll = 13.24 g
Molar mass of chlorophyll = 893.5 g/mol.
And mass of solvent i.e diethyl ether = 268.4 g = 0.2684 Kg (since 1 Kg = 1000 g)
