Formula of pyrite = FeS₂
Problem:
Weight fraction of Fe in FeS₂
Solution
Atomic mass of Fe = 55.845g/mol
Atomic mass of S = 32.065g/mol
To find the weight fraction of Fe in FeS₂:
Weight fraction =
}[/tex]
molar mass of FeS₂ = [55.845 + 2(32.065)] = 119.975g/mol
Weight fraction of Fe = 
As a percentage, weight fraction of Fe = 46.55%
