\(n_{CO_2}=\dfrac{2.688}{22.4}=0.12\left(mol\right)\)
\(n_{Ca\left(OH\right)_2}=0.1\cdot1=0.1\left(mol\right)\)
\(T=\dfrac{0.12}{0.1}=1.2\)
=> Tạo 2 muối
\(n_{CaCO_3}=a\left(mol\right),n_{Ca\left(HCO_3\right)_2}=b\left(mol\right)\)
Ta có :
\(a+b=0.1\)
\(a+2b=0.12\)
\(\Rightarrow\left\{{}\begin{matrix}a=0.08\\b=0.02\end{matrix}\right.\)
\(m_{Ca\left(HCO_3\right)_2}=0.02\cdot162=3.24\left(g\right)\)
\(n_{CO_2}=\dfrac{5.04}{22.4}=0.225\left(mol\right)\)
\(n_{Ba\left(OH\right)_2}=0.25\cdot0.5=0.125\left(mol\right)\)
\(T=\dfrac{0.225}{0.125}=1.8\)
=> Tạo ra 2 muối
\(n_{BaCO_3}=a\left(mol\right),n_{Ba\left(HCO_3\right)_2}=b\left(mol\right)\)
Ta có :
\(a+b=0.125\)
\(a+2b=0.225\)
\(\Rightarrow\left\{{}\begin{matrix}a=0.025\\b=0.1\end{matrix}\right.\)
\(m_{Muối}=0.025\cdot197+0.1\cdot259=30.825\left(g\right)\)
