A 2.55 L sample of gas at STP contains hydrogen and oxygen
gases. The mole fraction of hydrogen is 0.60. When the sample is
combusted to form water, calculate the mass of water formed,
assuming complete reaction.
1. Determine the mole fraction composition for the following mixture.
1. Determine the mole fraction composition for the following mixture.
The mixture solution is composed of two volatile components: Solute: pentane (72.0 g/mol) Solvent: hexane (86.0 g/mol)
The vapor pressures are the following: Solution: 258 torr Solute Pentane: 425 torr Solvent Hexane: 151 torr
Assume ideal behavior and that the mixture is at room temperature
The answer isXpentane = 0.391Xhexane = 0.609

mixture of 45 mole% n-hexane and 55 mole
% n-heptane is subjected to continuous
fraction in a tray column at 1 atm total
pressure. The distillate contains 95% n-hexane
and the residue contains 5% n-hexane. The
feed is saturated liquid. A reflux ratio of 2.5 is
used. The relative volatility of n-hexane in
mixture is 2.36. Determine the number of ideal
trays required.

A mixture of gases in a container acts as if it is a single gas
unless there is a chemical reaction going on. What does this say
about a sample of air? Do we have to measure the properties for the
nitrogen portion separately from the oxygen, carbon dioxide, and
water vapor portions?
