Gọi \(n_{N_2};n_{O_2}\) lần lượt là a,b (a,b > 0)
\(d^X/H_2=15,09\Rightarrow\overline{M}_X=30,18\)
\(\Rightarrow\dfrac{28a+32b}{a+b}=30,18\)
\(\Leftrightarrow28a+32b=30,18a+30,18b\)
\(\Leftrightarrow2,18a=1,82b\Leftrightarrow\dfrac{a}{b}\approx0,8=\dfrac{4}{5}\)
\(\Rightarrow\%V_{N_2}=44,44\%\Rightarrow\%V_{O_2}=55,56\%\)
