\(SNT,PT_K=n.N=2.6.10^{23}=1,2.10^{24}\)
\(SNT,PT_{N_2}=n.N=6.10^{23}.1,25=7,5.10^{23}\)
\(SNT,PT_{CaO}=n.N=6.10^{23}.6=3,6.10^{24}\)

\(n_{CO}=\dfrac{m}{M}=\dfrac{28}{28}=1\left(mol\right)\Rightarrow V_{CO}=22,4.n=22,4.1=22,4\left(l\right)\)
\(n_{H_2}=\dfrac{m}{M}=\dfrac{4}{2}=2\left(mol\right)\Rightarrow V_{H_2}=22,4.n=22,4.2=44,8\left(l\right)\)
\(n_{Cl_2}=\dfrac{m}{M}=\dfrac{35,5}{71}=0,5\left(mol\right)\Rightarrow V_{Cl_2}=22,4.n=22,4.0,5=11,2\left(l\right)\)
