\(n_{H2}=\dfrac{5,6}{22,4}=0,25\left(mol\right)\)
a) Pt : \(Zn+2HCl\rightarrow ZnCl_2+H_2|\)
1 2 1 1
0,25 0,5 0,25
b) \(n_{HCl}=\dfrac{0,25.2}{1}=0,5\left(mol\right)\)
500ml = 0,5l
\(C_{M_{ddHCl}}=\dfrac{0,5}{0,5}=1\left(M\right)\)
c) \(n_{Zn}=\dfrac{0,5.1}{2}=0,25\left(mol\right)\)
⇒ \(m_{Zn}=0,25.65=16,25\left(g\right)\)
