Quá trình sản xuất từ \(FeS_2\rightarrow H_2SO_4\)
\(n_{FeS_2}=\dfrac{120}{120}=1\left(mol\right)\\ BTnguyêntố\left(S\right)\Rightarrow n_{FeS_2}.2=n_{H_2SO_4\left(lt\right)}.1\\ \Rightarrow n_{H_2SO_4\left(lt\right)}=2\left(mol\right)\\ \Rightarrow H=\dfrac{m_{H_2SO_4\left(tt\right)}}{m_{H_2SO_4\left(lt\right)}}.100=\dfrac{170}{2.98}.100=86,74\%\)
