\(n_{H_2}=\dfrac{12.10^{22}}{6.10^{23}}=0,2\left(mol\right)\)
\(n_{SO_2}=\dfrac{3,2}{64}=0,05\left(mol\right)\)
=> Vhh = 0,25.22,4 + 4,48 + 0,2.22,4 + 0,05.22,4 = 15,68(l)
\(V_{O_2}=0,25.22,4=5,6l\)
\(V_{H_2}=\left(\dfrac{1,2.10^{23}}{6.10^{23}}\right).22,4=4,48l\)
\(V_{SO_2}=\left(\dfrac{3,2}{64}\right).22,4=1,12l\)
=> Vhh = 5,6 + 4,48 + 4,48 + 1,12 = 15,68 lít
