\(n_{CO2}=\dfrac{2,24}{22,4}=0,1\left(mol\right)\)
a) Pt : \(CO_2+Ba\left(OH\right)_2\rightarrow BaCO_3+H_2O\)
Theo Pt : \(n_{CO2}=n_{Ba\left(OH\right)2}=n_{BaCO3}=0,1\left(mol\right)\)
b) \(V_{ddBa\left(OH\right)2}=\dfrac{0,1}{1}=0,1\left(l\right)\)
c) \(m_{kt}=m_{BaCO3}=0,1.197=19,7\left(g\right)\)
