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
Answered by DrBob222
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.
