FROM THE REACTION we are observing that from 6 mole of haematite 4 moles of magnetite is being produced so from one mole 4/6 =0.667 mole of magnetite will be produced.

It's based on simple stoichiometry and mole concept..... Clearly in the following reaction, 6 moles of hematite is producing 4 moles of magnetite, so by mole Concept 1 mole of hema...
