Ta có: mFeS2 = 3.85% = 2,55 (tấn) = 2550000 (g)
\(\Rightarrow n_{FeS_2}=\dfrac{2550000}{120}=21250\left(mol\right)\)
Cách 1:
BTNT S, có: \(n_{SO_2}=2n_{FeS_2}=42500\left(mol\right)\)
\(\Rightarrow m_{SO_2\left(LT\right)}=4080000\left(g\right)=4,08\left(tan\right)\)
Mà: H% = 90%
\(\Rightarrow m_{SO_2\left(TT\right)}=4,08.09\%=3,672\left(tan\right)\)
Cách 2:
PT: \(4FeS_2+11O_2\underrightarrow{t^o}2Fe_2O_3+8SO_2\)
Theo PT: \(n_{SO_2\left(LT\right)}=2n_{FeS_2}=21250\left(mol\right)\)
\(\Rightarrow m_{SO_2\left(LT\right)}=4080000\left(g\right)=4,08\left(tan\right)\)
Mà: H% = 90%
\(\Rightarrow m_{SO_2\left(TT\right)}=3,672\left(tan\right)\)
