1. A 10.75 mol sample
of argon gas is maintained in
a 0.8053 L container
at 296.9 K. What is the pressure in atm
calculated using the van der Waals' equation
for Ar gas under these conditions?
For Ar, a
= 1.345 L2atm/mol2 and
b
= 3.219×10-2 L/mol
= ______ atm
2. The average molecular speed in a sample of CO2 gas
at a certain temperature is 408 m/s.
The average molecular speed in a sample of Ne gas is
______m/s at the same temperature.
