1)
\(d_{SO_2/kk}=\dfrac{64}{29}\approx2,21\)
\(d_{N_2O/kk}=\dfrac{44}{29}\approx1,52\)
2)
\(d_{N_2/CO_2}=\dfrac{28}{44}\approx0,64\) \(d_{N_2/O_2}=\dfrac{28}{32}=0,875\)
\(d_{H_2/CO_2}=\dfrac{2}{44}\approx0,05\) \(d_{H_2/O_2}=\dfrac{2}{32}=0,0625\)
Câu 1 :
Coi
\(n_{SO_2} = n_{N_2O} = 1\ mol\\ M_{hỗn\ hợp} = \dfrac{64+44}{1+1} = 54(g/mol)\\ \Rightarrow d_{hh/không\ khí} = \dfrac{54}{29} = 1,86\)
Câu 2 :
Coi :
\(n_{N_2} = n_{H_2} = 1\ mol\\ M_{hỗn\ hợp} = \dfrac{28 + 2}{1 + 1} = 15(g/mol)\)
Suy ra :
\(d_{hh/CO_2} = \dfrac{15}{44} = 0,34\\ d_{hh/O_2} = \dfrac{15}{32} = 0,46875\)
