1.A mixture of helium and nitrogen gases is maintained in a 7.60 L flask at a pressure of 2.43 atm and a temperature of 31 °C. If the gas mixture contains 1.35 grams of helium, the number of grams of nitrogen in the mixture is ------------- g.
2.A mixture of nitrogen and
krypton gases at a total pressure of
897 mm Hg contains nitrogen at a
partial pressure of 348 mm Hg. If the gas mixture
contains 2.22 grams of nitrogen,
how many grams of krypton are
present?-------------g Kr
3.Compute the root-mean-square speed of Ar molecules in a sample of argon gas at a temperature of 97°C.------------- m s-1
4.According to the ideal gas law, a 9.082 mol sample of methane gas in a 0.8470 L container at 504.4 K should exert a pressure of 443.8 atm. What is the percent difference between the pressure calculated using the van der Waals' equation and the ideal pressure? For CH4 gas, a = 2.253 L2atm/mol2 and b = 4.278×10-2 L/mol.--------------%
