Tutorial 4: Chapter 4 States of Matter
1.
Hydrogen gas occupies a 3.60 L container at 760 torr. Calculate the volume it occupies at
2.25 atm at a constant temperature.
(1.6 L)
2.
Nitrogen gas contained in a 1.85 L vessel exerts a pressure of 1.00 atm at 0 oC. Determine the required change in temperature to increase the pressure of nitrogen gas to 1.65 atm after it has been transferred to a 1.50 L vessel.
(92.297)
3.
An empty tank of 3 dm3 has a mass of 897.3 g. It is filled with propane gas, C3H8, at 25 o C to a pressure of 3.30 atm. Calculate the mass of the tank after it is filled.
(Assuming that the expansion of the tank from an increase in temperature is negligible)
(915.141 g)
4.
A mixture of noble gases contains 4.46 moles of Neon and 0.74 moles of Krypton and y mole of Xenon at a pressure of 2 atm.
(a)
Determine y mole of Xenon if the partial pressure of Neon is 1.214 atm.
(2.148 moles)
(b)
Determine the partial pressure of Krypton.

(0.2 atm)
5.
Calculate the number of moles of sulfur dioxide gas, SO2, transported in a 2 L container at s.t.p.
(0.089 mole)
6.
Water has a vapour pressure of 24 mm Hg at 25 °C and 182 mm Hg at 67 °C. Calculate the heat of vaporization.
[Sep 2011]
(40.685 kJ mole-1)
