\(n_{CO_2}=\dfrac{1,2395}{24,79}=0,05\left(mol\right)\)
PTHH: \(CaCO_3+2HCl\rightarrow CaCl_2+CO_2+H_2O\)
0,05<------0,1<-----0,05<----0,05
\(C_{M\left(HCl\right)}=\dfrac{0,1}{0,1}=1M\)
b) \(m_{CaCO_3}=0,05.100=5\left(g\right)\); \(m_{CaCl_2}=12,2-5=7,2\left(g\right)\)
\(m_{CaCl_2\left(sau.pư\right)}=0,05.111+7,2=12,75\left(g\right)\)
