\(CT:\overline{M}_2CO_3\)
\(n_{CO_2}=\dfrac{2.24}{22.4}=0.1\left(mol\right)\)
\(\overline{M}_2CO_3+2HCl\rightarrow2\overline{M}Cl+CO_2+H_2O\)
\(.............0.2..............0.1.....0.1\)
\(m_{HCl}=0.2\cdot36.5=7.3\left(g\right)\)
\(m_{CO_2}=0.1\cdot44=4.4\left(g\right)\)
\(m_{H_2O}=0.1\cdot18=1.8\left(g\right)\)
\(BTKL:m_{hh}+m_{HCl}=m_{Muối}+m_{CO_2}+m_{H_2O}\)
\(\Leftrightarrow8.9+7.3=m_{Muối}+4.4+1.8\)
\(\Leftrightarrow m_{muối}=8.9+7.3-4.4-1.8=10\left(g\right)\)
