\(n_{Cu}=\dfrac{8.32}{64}=0.13\left(mol\right)\)
\(Đặt:n_{NO}=a\left(mol\right),n_{NO_2}=b\left(mol\right)\)
\(\Rightarrow a+b=0.22\left(1\right)\)
\(BTe:\)
\(2\cdot0.13=3a+b\left(2\right)\)
\(\left(1\right),\left(2\right):a=0.02,b=0.2\)
\(\overline{M}=\dfrac{0.02\cdot30+0.2\cdot46}{0.22}=44.55\left(\dfrac{g}{mol}\right)\)
\(\Rightarrow C\)
