\(n_{H_2}=\dfrac{3.36}{22.4}=0.15\left(mol\right)\)
\(n_{Cl_2}=\dfrac{3.36}{22.4}=0.15\left(mol\right)\)
\(M_xO_y+yH_2\underrightarrow{t^o}xM+yH_2O\)
\(n_{O\left(oxit\right)}=n_{H_2O}=n_{H_2}=0.15\left(mol\right)\)
\(\Rightarrow m_M=m_{oxit}-m_O=12-0.15\cdot16=9.6\left(g\right)\)
\(2M+nCl_2\underrightarrow{t^o}2MCl_n\)
\(\dfrac{0.3}{n}....0.15\)
\(M_M=\dfrac{9.6}{\dfrac{0.3}{n}}=32n\)
\(BL:\) \(n=2\Rightarrow M=64\)
