a) \(n_{ZnO}=\dfrac{4,32}{81}=\dfrac{4}{75}\left(mol\right)\)
PTHH: \(ZnO+2HCl\rightarrow ZnCl_2+H_2O\)
\(\dfrac{4}{75}\)---->\(\dfrac{8}{75}\)------->\(\dfrac{4}{75}\)---->\(\dfrac{4}{75}\)
\(\Rightarrow m_{ZnCl_2}=\dfrac{4}{75}.136=\dfrac{544}{75}\left(g\right)\)
b) \(m_{H_2O}=\dfrac{4}{75}.18=0,96\left(g\right)\)
Mà \(d_{H_2O}=1g/ml\)
=> \(V_{H_2O}=\dfrac{0,96}{1}=0,96\left(ml\right)\)
c) \(m_{HCl}=\dfrac{8}{75}.36,5=\dfrac{292}{75}\left(g\right)\)
\(\Rightarrow C\%_{dd.HCl}=\dfrac{\dfrac{292}{75}}{200}.100\%=\dfrac{146}{75}\%\)
