Question

50 mL of a gaseous hydrocarbon is mixed with excess of oxygen and burnt and cooled to the laboratory temperature.The reduction in volume was found to be 150mL. The gas is then passed through caustic potaash, when there is a further reduction of 150mL. Provided all the volumes are measured at same conditions of temperature and pressure, find out the molecular formula of the hydrocarbon.
