London is such an attractive place that it attracts millions of people every years

a) \(n_{Zn}=\dfrac{3,36}{22,4}=0,15\left(mol\right)\)

PTHH: Zn + H₂SO₄ --> ZnSO₄ + H₂

_____0,15<-------------0,15<---0,15

=> m_Zn = 0,15.65 = 9,75(g)

=> \(\left\{{}\begin{matrix}\%Zn=\dfrac{9,75}{17,75}.100\%=54,93\%\\\%Cu=100\%-54,93\%=45,07\%\end{matrix}\right.\)

b) m_ZnSO4 = 0,15.161=24,15(g)
