Đổi 2,4 tấn = 2400 kg
Ta có: \(n_{FeS_2}=\dfrac{2400\cdot60\%}{120}=12\left(kmol\right)\)
Bảo toàn nguyên tố: \(n_{H_2SO_4\left(lý.thuyết\right)}=2n_{FeS_2}=24\left(kmol\right)\)
\(\Rightarrow n_{H_2SO_4\left(thực\right)}=24\cdot80\%=19,2\left(kmol\right)\) \(\Rightarrow m_{ddH_2SO_4}=\dfrac{19,2\cdot98}{70\%}=2688\left(kg\right)\)
\(\Rightarrow V_{H_2SO_4}=\dfrac{2688}{1,8}\approx1493,3\left(l\right)\)
