If anyone knows how to do this problem, could you please give me some hints?? I don’t need the answer just some help as to where to start.... Metallic molybdenum can be produced from the mineral molybdenite, MoS2. The mineral is first oxidized in air to molybdenum trioxide and sulfur dioxide. Molybdenum trioxide is then reduced to metallic molybdenum using hydrogen gas. The balanced equations are: MoS2 (g) + 7/2 O2 (g) -------> MoO3 (s) + 2SO2 (g) MoO3 (s) + 3H2 (g) ------------> Mo (s) + 3H2O (l) Calculate the volumes of air and hydrogen gas at 17 deg. C and 1.00 atm that are neccessary to produce 1.00 x 10^3 kg of pure molybdenum from MoS2 . Assume air contains 21% oxygen by volume and assume 100% yield for each reaction.
