\(n_{O2}=\dfrac{16,8}{22,4}=0,75\left(mol\right)\)
\(m_{O2}=0,75.32=24\left(g\right)\)
⇒ \(M_{O2}=\dfrac{24}{0,75}=32\)(g/mol)
\(n_{SO2}=\dfrac{10,08}{22,4}=0,45\left(mol\right)\)
\(m_{SO2}=0,45.64=28,8\left(g\right)\)
⇒ \(M_{SO2}=\dfrac{28,8}{0,45}=64\)(g/mol)
\(n_{Cl2}=\dfrac{7,84}{22,4}=0,35\left(mol\right)\)
\(m_{Cl2}=0,35.71=24,85\left(g\right)\)
⇒ \(M_{Cl2}=\dfrac{24,85}{0,35}=71\)(g/mol)
