\(V_A=V_{O_2}\Rightarrow n_A=n_{O_2}=\frac{0,16}{32}=0,005\) mol
\(\Rightarrow M_A=\frac{0,3}{0,005}=60\) g/mol
\(C_xH_yO_z+\left(x+\frac{y}{4}-\frac{z}{2}\right)O_2\Rightarrow xCO_2+\frac{y}{2}H_2O\)
\(1x\frac{y}{2}\)
\(0,005\frac{0,44}{44}=0,01\frac{0,18}{18}=0,01\)
\(\Rightarrow\frac{1}{0,005}=\frac{x}{0,01}=\frac{\frac{y}{2}}{0,01}=\Rightarrow x=2;y=4\)
\(\Rightarrow\) CTPT : \(C_2H_4O_z\Rightarrow28+16z=60\Rightarrow z=2\Rightarrow\) CTPT : \(C_2H_4O_2\)
