`5 mL` of a gaseous hydrocarbon was exposed to `30 mL` of `O_(2)`. The resultant gas, on cooling, is formed to measure `25 mL` of which `10 mL` is absrobed by `NaOH` and the remainder by pyrogallol. Determine the molecular formula of hydrocarbon. All measurements are made at constant pressure and temperature.
