50cc of oxygen is collected in an inverted gas jar over water.The atmospheric pressure is 99.4 kPa and the room tempareture is 27^(@)C. The water level in the jar is same as the level outside . The saturation vapour pressure at 27^(@)C is 3.4kPa. Calculate the number of moles of oxgen collected in the jar.
