An organic compound (CxH2yOy) was burnt with twice the amount of oxygen needed for complete combustion to CO2 and H2O. The hot gases when cooled to 0°C and 1 atm pressure, measured 2.24 L. The water collected during cooling weigh 0.9 g. The vapour pressure of pure water at 20°C is 17.5 mm Hg and is lowered by 0.104 mm Hg when 50g of the organic compound are dissolved in 1000g of water. Give the molecular formula of the organic compound.
