Given that the density of air at 0.987 bar and 27°C is 1.146 kg m−3, calculate the mole fraction and partial pressure of nitrogen and oxygen assuming the following conditions.
(a) air consists only of these two gases
mole fraction nitrogen
mole fraction oxygen
partial pressure nitrogen
bar
partial pressure oxygen
bar
(b) air also contains 1.0 mole percent Ar
mole fraction nitrogen
mole fraction oxygen
partial pressure nitrogen
bar
partial pressure oxygen
bar
partial pressure argon
bar
