In the determination of the molecular weight of chloroform vapour by Hofmann's method, the
following results were obtained:
Weight of liquid in bulb = 0.2704 g; Volume of vapour = 110 cm³; Temperature of vapour
99.6 °C; Atmospheric pressure = 747 mmHg; Vapour pressure of water vapour at 99.6 °C =
285.2 mmHg. Calculate the relative molecular weight of chloroform if 1dm³ of H2 at S. T.P.
weighs 0.09 g. In your calculations, show your work clearly including manipulations of units.
