Reaction
4 FeCO₃ + O₂ ⇒ 2 Fe₂O₃ + 4CO₂
MW FeCO₃ : 115,854 g/mol
MW Fe₂O₃ : 159,69 g/mol
[tex]\tt \dfrac{35}{115.854}=0.302[/tex]
[tex]\tt \dfrac{2}{4}\times 0.302=0.151[/tex]
[tex]\tt 0.151\times 159.69=24.113~g[/tex]
[tex]\tt \dfrac{22.5}{24.113}\times 100\%=93.3\%[/tex]
mol of 1 kg Fe₂O₃ = 1000 g
[tex]\tt \dfrac{1000}{159.69}=6.262[/tex]
mol of FeCO₃
[tex]\tt \dfrac{4}{2}\times 6.262=12.524[/tex]
mass of FeCO₃
[tex]\tt 12.524\times 115.854=1450.955~g[/tex]
a purity of 62.8%
[tex]\tt \dfrac{100}{62.8} \times 1450.955=2310.44~g[/tex]
