\(n_{CO_2}=\dfrac{4,48}{22,4}=0,2\left(mol\right)\)
\(n_{Ca\left(OH\right)_2}=0,1.0,5=0,05\left(mol\right)\)
Xét \(\dfrac{n_{CO_2}}{n_{Ca\left(OH\right)_2}}=\dfrac{0,2}{0,05}=4\)
=> Tạo ra muối HCO3-
PTHH: Ca(OH)2 + 2CO2 --> Ca(HCO3)2
______0,05------------------->0,05
=> mCa(HCO3)2 = 0,05.162=8,1(g)
