A) A mixture of hydrogen and argon gases is maintained in a 6.47 L flask at a pressure of 3.43 atm and a temperature of 85 °C. If the gas mixture contains 1.10 grams of hydrogen, the number of grams of argon in the mixture is _______ g.
B) Oxygen gas can be prepared by heating potassium chlorate according to the following equation:
2KClO3(s) ---------> 2KCl(s) + 3O2(g)
The product gas, O2, is collected over water at a temperature of 25 °C and a pressure of 747 mm Hg. If the wet O2 gas formed occupies a volume of 9.38L, the number of grams of O2 formed is _______ g. The vapor pressure of water is 23.8 mm Hg at 25 °C.
