4FeS2 + 11O2 \(\underrightarrow{to}\) 2Fe2O3 + 8SO2
\(n_{FeS_2}=\frac{6}{120}=0,05\left(mol\right)\)
Theo PT: \(n_{Fe_2O_3}=\frac{1}{2}n_{FeS_2}=\frac{1}{2}\times0,05=0,025\left(mol\right)\)
\(\Rightarrow m_{Fe_2O_3}=0,025\times160=4\left(g\right)\)
Theo pT: \(n_{SO_2}=2n_{FeS_2}=2\times0,05=0,1\left(mol\right)\)
\(\Rightarrow V_{SO_2}=0,1\times22,4=2,24\left(l\right)\)
\(n_{FeS_2}=\frac{6}{120}=0,05mol\)
PTHH : \(4FeS_2+11O_2\underrightarrow{t^o}2Fe_2O_3+8SO_2\)
Theo PTHH :

\(n_{Fe_2O_3}=\frac{2}{4}n_{FeS_2}=\frac{1}{2}n_{FeS_2}=\frac{1}{2}.0,05=0,025mol\) \(\Rightarrow m_{Fe_2O_3}=0,025.160=4g\)
