Chlorine gas was first prepared in 1774 by the oxidation of NaCl with MnO2: 2NaCl (s) + 2H2SO4 (l) + MnO2 (s) ---> Na2SO4 (s) + MnSO4 (s) + 2H2O (g) + Cl2 (g) Assume that the gas produced is saturated with water vapor at a partial pressure of 28.7 mm Hg and that it has a volume of 0.597L at 27C and 755 mm Hg pressure.a) What is the mole fraction of Cl2 in the gas?b) How many grams of NaCl were used in the experiment, assuming complete reaction?
