\(n_{H_2}=\dfrac{37,185}{24,79}=1,5mol\\ Fe+2HCl\rightarrow FeCl_2+H_2\\ n_{Fe}=n_{H_2}=1,5mol\\ m_{Fe}=1,5.56=84g\)
PT: \(Fe+2HCl\rightarrow FeCl_2+H_2\)
Ta có: \(n_{H_2}=\dfrac{37,185}{24,79}=1,5\left(mol\right)\)
Theo PT: \(n_{Fe}=n_{H_2}=1,5\left(mol\right)\)
\(\Rightarrow m_{Fe}=1,5.56=84\left(g\right)\)
