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.

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
