Metallic molybdenum can be produced from the mineral molybednite, MoS2. The mineral is first oxidized Im air to molybdenum trioxide and sulfur dioxide. Molybdenum trioxide is then reduced to metallic molybdenum using hydrogen gas and yielding water as the other product. Calculate the volumes of air and H2 at 17°C and 1.00 atm that are necessary to produce 1.00 x 10’ kg of pure Mo from MOS2. Assume that air contains 21% oxygen by volume and also assume that both the oxidation and reduction reactions are quantitative.

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
