\(V\%_{NxO}=n\%_{NxO}=100\%-50\%-25\%=25\%\)
\(\Rightarrow n_{NxO}=1.25\%=0,25\)
\(\left\{{}\begin{matrix}n_{NO}=0,5\left(mol\right)\\n_{NO2}=0,25\left(mol\right)\end{matrix}\right.\)
Ta có:
\(\%m_{NO}=40\%\)
\(\Leftrightarrow\frac{0,5.30}{0,5.30+0,25.46+0,25.\left(14x+16\right)}=40\%\)
\(\Leftrightarrow x=2\)
Vậy CTHH: N2O
