\(n_{Cl_2}=a\left(mol\right)\)
\(n_{O_2}=b\left(mol\right)\)
\(n_Y=a+b=\dfrac{5.6}{22.4}=0.25\left(mol\right)\left(1\right)\)
\(m_Y=71a+32b=12.8\left(g\right)\left(2\right)\)
\(\left(1\right),\left(2\right):a=\dfrac{8}{65},b=\dfrac{33}{260}\)
\(n_{Cl_2}+n_{O_2}=\dfrac{5,6}{22,4}=0,25\left(mol\right)\left(1\right)\)
\(71n_{Cl_2}+32n_{O_2}=12,8\left(g\right)\left(2\right)\)
Giải hệ hai phương trình (1) và (2) ta được:
\(\left\{{}\begin{matrix}n_{Cl_2}=0,123\left(mol\right)\\n_{O_2}=0,127\left(mol\right)\end{matrix}\right.\)
