\(n_{SO_2}=\dfrac{3.36}{22.4}=0.15\left(mol\right)\)
\(n_{OH^-}=0.5\cdot0.2+0.5\cdot0.2=0.2\left(mol\right)\)
\(T=\dfrac{0.2}{0.15}=1.33\)
=> Tạo ra \(SO_3^{2-},HSO_3^-\)
Đặt :
\(n_{SO_3^{2-}}=a\left(mol\right),n_{HSO_3^{2-}}=b\left(mol\right)\)
Ta có hệ phương trình :
\(\left\{{}\begin{matrix}n_S=a+b=0.15\left(mol\right)\\n_{OH^-}=2a+b=0.2\left(mol\right)\end{matrix}\right.\)
\(\Rightarrow\left\{{}\begin{matrix}a=0.05\\b=0.1\end{matrix}\right.\)
\(m_{Muối}=m_{Na^+}+m_{K^+}+m_{SO_3^{2-}}+m_{HSO_3^-}\)
\(=0.5\cdot0.2\cdot23+0.5\cdot0.2\cdot39+0.05\cdot80+0.1\cdot81=18.3\left(g\right)\)
