1.  A gas mixture consists of 60.0% Ar, 30.0% Ne, and 10.0% Kr
by volume.
If the pressure of this gas mixture is 80.0 kPa, what is the partial
pressure
of each of the gases?

2.  The total pressure of a mixture of H_{2}, He, and
Ar is
99.3 kPa. The partial pressure of the He is 42.7 kPa, and the partial
pressure
of Ar is 54.7 kPa. What is the partial pressure of hydrogen?

3.  A cylinder contains 40 g of He, 56 g of N_{2}, and
40 g
of Ar.

(a) How many moles of each gas are in the
mixture?
(b) If the total pressure of the mixture is 10
atm, what
is the partial pressure of He?


4.  What is the partial pressure of each gas in a mixture
which contains
40 g of He, 56 g of N_{2}, and 16 g of O_{2}, if the
total
pressure of the mixture is 5 atmospheres?

5.  The composition of dry air by volume is 78.1% N_{2},
20.9%
O_{2}, and 1% other gases. Calculate the partial pressures, in
atmospheres and kPa, in a tank of dry air compressed to 10.0
atmospheres.
