\(n_{Zn}=\dfrac{6,5}{65}=0,1\left(mol\right)\)
a) Pt : \(Zn+2HCl\rightarrow ZnCl_2+H_2|\)
1 2 1 1
0,1 0,1 0,1
b) n\(n_{H2}=\dfrac{0,1.1}{1}=0,1\left(mol\right)\)
\(V_{H2\left(dktc\right)}=0,1.22,4=2,24\left(l\right)\)
\(n_{ZnCl2}=\dfrac{0,1.1}{1}=0,1\left(mol\right)\)
⇒ \(m_{ZnCl2}=0,1.136=13,6\left(g\right)\)
