1) \(n_{Zn}=\frac{1,5.10^{23}}{6.10^{23}}=0,25\left(mol\right)\)
\(m_{Zn}=0,25.65=16,25\left(g\right)\)
2) \(n_{NH_3}=\frac{3.10^{23}}{6.10^{23}}=0.5\left(mol\right)\)
\(m_{NH_3}=0,5.17=8,5\left(g\right)\)
3) \(m_{H2SO4}=0,45.98=44,2\left(g\right)\)
4) \(n_{NO2}=\frac{6,72}{22,4}=0,3\left(mol\right)\)
\(m_{NO2}=0,3.46=13,8\left(g\right)\)
5) \(n_{O_2}=\frac{2,24}{22,4}=0,1\left(mol\right)\)
\(n_{H_2}=\frac{3,36}{22,4}=0,15\left(mol\right)\)
\(m_{hh}=0,1.32+0,15.2=3,5\left(g\right)\)
