Amixture 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.
