Sulfur is used in the production of vulcanized rubber, detergents, dyes, pharmaceuticals, insecticides, and many other substances. The final step in the Claus method for making sulfur is
SO2(g) + 2H2S(g) ==> 3S(s) + 2H2O(l)
a) What minimum volume of sulfur dioxide at STP would be necessary to produce 82.5 kg of sulfur?
b) What maximum mass of sulfur in kg could be produced by the reaction of 1.3 x 10 4(the 4th) m3 of SO2(g) with 2.5 x 10 4(the 4th) m3 of H2S(g), both at STP?
