A flask which contains benzaldehyde is connected to an open-ended water manometer. The atmospheric pressure is 760 mmHg. The height of the water in the manometer arm which is connected to the flask is 1048 mm and the height in the open-ended arm is 76 mm when the temperature in the flask is 47.8 . The height of the water in the manometer arm which is connected to the flask is 875 mm and the height in the open-ended arm is 176 mm when the temperature in the flask is 101 .
a_What is the vapor pressure of benzaldehyde at 85 (Use Clausius-Clapeyron Equation)?
b_Air saturated with benzaldehyde at 85 and 101.3 kPa is cooled to 47.8 at constant pressure. Estimate the percentage of the benzaldehyde originally in the vapor that condenses.
