15.8kg of Iron pyrite, FeS2, is converted to iron metal. What mass of iron metal is obtained

[From: ] [author: ] [Date: 12-05-13] [Hit: ]
8 + 64.fraction of Fe in FeS2 = 55.8 ÷ (55.8 + 64.Mass of Fe = [55.8 ÷ (55.......
Mass of Fe = fraction of Fe in FeS2 * 15.8 kg
Determine the fraction of Fe in FeS2

Fe = 55.8
S2 = 2 * 32.1 = 64.2
FeS2 = 55.8 + 64.2
fraction of Fe in FeS2 = 55.8 ÷ (55.8 + 64.2)

Mass of Fe = [55.8 ÷ (55.8 + 64.2)] * 15.8
