a.

\(V_{H_2S}=0.75\cdot22.4=16.8\left(l\right)\)

\(V_{SO_2}=\dfrac{12.8}{64}\cdot22.4=4.48\left(l\right)\)

\(V_{O_2}=\dfrac{3.2}{32}\cdot22.4=2.24\left(l\right)\)

b.

\(n_{hh}=\dfrac{22}{44}+\dfrac{3.55}{71}+\dfrac{0.14}{28}=0.555\left(mol\right)\)

\(V_{hh}=0.555\cdot22.4=12.432\left(l\right)\)

ta có: n_Cl2=\(\frac{7,1}{71}=0,1mol\)

\(V_{Cl2}=0,1.22,4=2,24\left(l\right)\)

\(n_{CO2}=\frac{8,8}{44}=0,2\left(mol\right)\)

\(V_{CO2}=0,2.22,4=4,48\left(l\right)\)

\(n_{NO2}=\frac{4,6}{46}=0,1\left(mol\right)\)

\(V_{NO2}=0,1.22,4=2,24\left(l\right)\)

\(n_{h^2}=0,1+0,2+0,1=0,4\left(mol\right)\)

\(V_{h^2}=2,24+2,24+4,48=8,96\left(l\right)\)

b) ta có \(n_{O2}=\frac{16}{32}=0,5\left(mol\right)\)

\(n_{N2}=\frac{14}{28}=0,5\left(mol\right)\)

\(\Leftrightarrow n_{h^2}=0,5+0,5=1\left(mol\right)\)

c) vì \(S=n.6.10^{23}\Rightarrow n=\frac{S}{6.10^{23}}\)

\(n_{N2}=\frac{1,5.10^{23}}{6.10^{23}}=0,25\left(mol\right)\)

\(V_{N2}=0,25.22,4=5,6\left(l\right)\)

\(n_{CO2}=\frac{9.10^{23}}{6.10^{23}}=1,5\left(mol\right)\)

\(V_{CO2}=1,5.22,4=33,6\left(l\right)\)
