\(n_{H_2}=\dfrac{33,6}{22,4}=1,5\left(mol\right)\)
\(PTHH:Fe+H_2SO_4\rightarrow FeSO_4+H_2\uparrow\)
Theo PTHH: \(n_{H_2}=n_{Fe}=n_{H_2SO_4}=1,5\left(mol\right)\)
\(\Rightarrow m_{Fe}=1,5.56=84\left(g\right)\)
\(\Rightarrow CM_{H_2SO_4}=\dfrac{1,5}{0,5}=3M\)
Fe + H2SO4 → FeSO4 + H2
\(n_{H_2}=\dfrac{33,6}{22,4}=1,5\left(mol\right)\)
a) Theo PT: \(n_{Fe}=n_{H_2}=1,5\left(mol\right)\)
\(\Rightarrow m_{Fe}=1,5\times56=84\left(g\right)\)
b) Đổi: 500 ml = 0,5 l
Theo PT: \(n_{H_2SO_4}=n_{H_2}=1,5\left(mol\right)\)
\(\Rightarrow C_{M_{H_2SO_4}}=\dfrac{1,5}{0,5}=3\left(M\right)\)
