Question

What mass of Fe is in 316.80 g Fe2O3?

Answer 1

Hi there,

One mol of ferric oxide have 2 mols of iron

Fe2O3 => 2Fe

By molar mass

(56×2+16×3) = (2×56)

160 gm of Fe2O3= 112 gm of iron

So

316.80 gm of Fe2O3 = ???

So the mass of iron is

316.80× 112 ÷ 160 =

221.76 gm of iron

Hope the answer is helpful
