a) PTHH: Fe + H2SO4 → FeSO4 + H2
nH2=3,3622,4=0,15(mol)nH2=3,3622,4=0,15(mol)
b) Theo PT: nFepư=nH2=0,15(mol)nFepư=nH2=0,15(mol)
⇒mFepư=0,15×56=8,4(g)
Fe + H2SO4 → FeSO4 + H2
\(n_{H_2}=\dfrac{3,36}{22,4}=0,15\left(mol\right)\)
Theo PT: \(n_{Fe}pư=n_{H_2}=0,15\left(mol\right)\)
\(\Rightarrow m_{Fe}pư=0,15\times56=8,4\left(g\right)\)
