\(n_{H_2}=\dfrac{1,2.10^{23}}{6.10^{23}}=0,2\left(mol\right)\)
\(n_{SO_2}=\dfrac{6,4}{64}=0,1\left(mol\right)\)
=> Vhh = (1,5 + 2,5+ 0,2 +0,1).22,4 = 96,32(l)
mhh = 1,5.32 + 2,5.28 + 0,2.2 + 6,4 = 124,8(g)
a) \(n_{H_2}=\dfrac{1,2.10^{23}}{6.10^{23}}=0,2\left(mol\right)\); \(n_{SO_2}=\dfrac{6,4}{64}=0,1\left(mol\right)\)
V = (1,5 + 2,5 + 0,2 + 0,1).22,4 = 96,32 (l)
b) \(m_{hh}=1,5.32+2,5.28+0,2.2+6,4=124,8\left(g\right)\)
\(n_{SO_2}=\dfrac{6,4}{64}=0,1mol\)
\(n_{H_2}=\dfrac{1,2.10^{23}}{6.10^{23}}=0,2mol\)
\(\Rightarrow V_{hh}=\left(0,1+0,2+1,5+2,5\right).22,4=96,32l\)
\(m_{O_2}=1,5.32=48g\)
\(m_{N_2}=2,5.28=70g\)
\(m_{H_2}=0,2.2=0,4g\)
=> \(m_{hh}=48+70+0,4+6,4==124,8g\)
nX = 0,672/22,4 = 0,03 (mol)
Gọi nN2 = a (mol); nO2 = b (mol)
a + b = 0,03
28a + 32b = 0,88
=> a = 0,02 (mol); b = 0,01 (mol)
%VN2 = 0,02/0,03 = 66,66%
%VO2 = 100% - 66,66% = 33,34%
M(X) = 0,88/0,03 = 88/3 (g/mol)
nX = 2,2 : 88/3 = 0,075 (mol)

\(V_{H_2S}=0.75\cdot22.4=16.8\left(l\right)\)
\(V_{SO_2}=\dfrac{12.8}{64}\cdot22.4=4.48\left(l\right)\)
\(V_{O_2}=\dfrac{3.2}{32}\cdot22.4=2.24\left(l\right)\)
b.
\(n_{hh}=\dfrac{22}{44}+\dfrac{3.55}{71}+\dfrac{0.14}{28}=0.555\left(mol\right)\)
\(V_{hh}=0.555\cdot22.4=12.432\left(l\right)\)
\(n_{O_2}=2a\left(mol\right),n_{N_2}=3a\left(mol\right),n_{SO_2}=4a\left(mol\right)\)
\(n_{hh}=2a+3a+4a=9a\left(mol\right)\)
\(\Rightarrow9a=\dfrac{5.4\cdot10^{23}}{6\cdot10^{23}}=0.9\)
\(\Rightarrow a=9\)
\(V_{hh}=0.9\cdot22.4=20.16\left(l\right)\)
