\(n_{H_2}=\dfrac{1,2\times10^{23}}{6\times10^{23}}=0,2\left(mol\right)\)
\(n_{SO_2}=\dfrac{6,4}{64}=0,1\left(mol\right)\)
Ta có: \(V_{hh}=V_{O_2}+V_{N_2}+V_{H_2}+V_{SO_2}\)
\(\Leftrightarrow V_{hh}=22,4\times1,5+22,4\times2,5+22,4\times0,2+22,4\times0,1=96,32\left(l\right)\)
Ta có: \(m_{hh}=m_{O_2}+m_{N_2}+m_{H_2}+m_{SO_2}\)
\(\Leftrightarrow m_{hh}=1,5\times32+2,5\times28+0,2\times2+6,4=124,8\left(g\right)\)
