Question

Magnetite can be reduced with CO to yield iron metal and carbon dioxide. Calculate the mass of magnetite (in kg ) needed to obtain 4 kg of iron if the process is 80 \% efficient. [Atomic weight of Fe and O are 56g and 16g, respectively]

Accepted Answer

Correct answer: D. (d) Fe_3O_4 Magnetite+4 CO 3 Fe4 kg needed .+4 CO_2 MW of Fe_3O_4=232 g/ mol since the process has 80 \% efficiency then 232 g of magnetite is producing 3 56 0.8 g of Fe ∴ To obtain 4 kg of Fe, the amount of Fe_3O_4 required = 232 4 10^33 56 8 g=6.9 kg
