The easiest way is to determine the density of each of the possibilities. For example, oxygen would be
molar mass O2/22.4 = 32/22.4 = 1.43
CO2 would be 44/22.4 = 1.95 etc.
A sample of gas has density of 1.98 gram per DM cube at 273 Kelvin and 760 CMhg which of the following as it should be oxygen carbon dioxide zenone ethane
