PTHH: \(Zn+H_2SO_4\rightarrow ZnSO_4+H_2\uparrow\)
Ta có: \(\left\{{}\begin{matrix}n_{Zn}=\dfrac{26}{65}=0,4\left(mol\right)\\n_{H_2SO_4}=\dfrac{980\cdot10\%}{98}=1\left(mol\right)\end{matrix}\right.\) \(\Rightarrow\) Axit còn dư, Kẽm p/ứ hết
\(\Rightarrow n_{H_2}=0,4\left(mol\right)\) \(\Rightarrow V_{H_2}=0,4\cdot22,4=8,96\left(l\right)\)
