question

Lunar soil contains,ilmenite, a mineral with the composition FeO\bulletTiO_2. It has been suggested that moon explorers might obtain water and oxygen from lunar soil by reducing it with hydrogen (brought from earth) according to the following reactions. Beginning with soil heated to 1300°C in a solar furnace: FeTiO_3 + H_2-----------------\rightarrow H_2O + Fe + TiO_2 Electrolysis 2H_2O-----------------\rightarrow 2H_2O + O_2 How much water and oxygen could be obtained from 50 kg of soil if the soil is taken to be 5 per centilmenite?
