a) \(d_{khí/N_2}=\dfrac{M_{khí}}{M_{N_2}}=2\Rightarrow M_{khí}=2.M_{N_2}=2.28=56\left(g/mol\right)\)
\(d_{khí/N_2}=\dfrac{M_{khí}}{M_{N_2}}=207\Rightarrow M_{khí}=207.M_{N_2}=207.28=5796\left(g/mol\right)\)
b) \(d_{khí/kk}=\dfrac{M_{khí}}{M_{kk}}=2,45\Rightarrow M_{khí}=2,45.M_{kk}=2,45.29=71,05\left(g/mol\right)\)
\(d_{khí/kk}=\dfrac{M_{khí}}{M_{kk}}=0,965\Rightarrow M_{khí}=0,965.M_{kk}=0,965.29=28,035\left(g/mol\right)\)
