Ta có: \(n_{CaCO_3}=\dfrac{10}{100}=0,1\left(mol\right)\)
a, PT: \(CO_2+Ca\left(OH\right)_2\rightarrow CaCO_3+H_2O\)
______0,1______0,1_______0,1 (mol)
b, \(V_{CO_2}=0,1.22,4=2,24\left(l\right)\)
c, \(m_{Ca\left(OH\right)_2}=0,1.74=7,4\left(g\right)\)
\(\Rightarrow m_{ddCa\left(OH\right)_2}=\dfrac{7,4}{10\%}=74\left(g\right)\)
