The atomic weight of Fe2O3 is

2 x 55.84 +3 x 15.999 = 159.68

100 divided by 159.68 = 0.626 moles of Fe2O3

2 moles of Fe per mole of Fe2O3 is

2 x .626 moles of Fe. Multiply 0.626 times atomic weight of Fe is

0.626 x 55.84 = 34.97 grams of Fe in 100 grams of Fe2O3

no. of moles of Fe2O3 = 4500/ (2 x fifty 5.8 + sixteen.0 x 3) = 28.1955 mol. From the equation, reacting ratio of Fe2O3 : Fe = one million : 2 = 28.1955 mol : fifty six.3910 mol max mass of Fe attainable = fifty six.3910 x (fifty 5.8) = 3146.6 g
