For OCTANE, what is the ratio of Carbon atoms to Hydrogen atoms in a molecule?

It's specified that Octane undergoes complete combustion to form 8L of Carbon Dioxide & 9L of Water at constant temp and pressure.

thanks :)

CxHy + O2 ==> CO2 + H2O

If it forms 8L CO2 and 9L H2O, the ratio of C/H must be 8/(2*9) or 8/18
