A mixture of H2Ov, CO2 and N2 was trapped in a glass apparatus with a volume of 0.731 mL. The pressure of total mixture was 1.74 mm of Hg at 23°C. The sample was transferred to a bulb in contact with dry ice (-75°C) so that H2Ov are frozen out. When the sample returned to normal value of temperature, pressure was 1.32 mm of Hg. The sample was then transferred to a bulb in contact with liquid N2 (-95°C) to freeze out CO2. In the measured volume, pressure was 0.53 mm of Hg at original temperature. How many mole of each constituent are in mixture?
