An organic compound (Cx H2y Oy) 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 and pressure, measured 2.24 L. The water collected during cooling weigh 0.9g. The vapour pressure of pure water at 20°C is 17.5mm Hg and is lowered by 0.104mm rvhen 50g of the organic compound are dissolved in 1000 g of water. Give the molecular formula of the organic compound.
