Ta có:
\(n_{CO2}=n_{CaCO3}=\frac{60}{100}=0,6\left(mol\right)\)
\(m_{CO2}+m_{H2O}=37,2\left(g\right)\)
\(\Rightarrow m_{H2O}=10,8\left(g\right)\)
\(n_{H2O}=\frac{10,8}{18}=0,6\left(mol\right)\)
\(CTHH:C_xH_y\)
\(n_C=n_{CO2}=0,6\left(mol\right)\)
\(n_H=n_{H2O}=1,2\left(mol\right)\)
\(x=\frac{n_{CO2}}{n_A}=6\)
\(y=\frac{n_{H2O}}{n_A}=12\)
\(\Rightarrow CTPT:C_6H_{12}\)
