A mixture of 1 mol of He and 0.5 mol of SO2 is held in a container at a constant temperature of 27°C. The partial pressure of He is 2 atm. If the mixture behaves ideally, what is the density of the mixture (g/L) closest to? (Given: R = 0.082 L atm/mol K, Molar mass of He = 4 g/mol, Molar mass of SO2 = 64 g/mol)
2.93 g/L
3.20 g/L
2.75 g/L
3.05 g/L
A real gas deviates most from ideal behavior at:
High temperature and low pressure
Low temperature and high pressure
High temperature and high pressure
Low temperature and low pressure
Two flasks A and B have equal volumes. Flask A contains H2 at 2 atm and 300K. Flask B contains an equal mass of CH4 at 600 K. Assuming ideal behavior, the ratio of the number of molecules in flask A to flask B is:

2:1
8:1
16:1
The compressibility factor (Z) for a gas is given by . At high pressures, attractive forces between gas molecules become significant. For a gas exhibiting strong intermolecular attractions, at moderately high pressure, Z will be:
Greater than 1
Less than 1
Equal to 1
Zero
Equal masses of three gases A, B, and C are kept in separate containers of equal volume at the same temperature. The pressure in the containers are in the ratio of 1:16:9. The ratio of their molar masses is:
