CO2 : \(n_{CO_2}=\dfrac{5.28}{44}=0.12\left(mol\right)\)
\(\%C=\dfrac{0.2\cdot12}{5.28}\cdot100\%=45.45\%\)
\(\%H=100\%-45.45\%=54.55\%\)
H2O : \(n_{H_2O}=\dfrac{3.24}{18}=0.18\left(mol\right)\)
\(\%H=\dfrac{0.18\cdot2}{3.24}\cdot100\%=11.11\%\)
\(\%O=100\%-11.11\%=88.89\%\)
SO2 : \(n_{SO_2}=\dfrac{3.54}{64}=\dfrac{177}{3200}\left(mol\right)\)
\(\%S=\dfrac{\dfrac{177}{3200}\cdot32}{3.54}\cdot100\%=50\%\)
\(\%O=100\%-50\%=50\%\)
