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.

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
