A. Consider a sample of 3.5g of water, which has an equilibrium vapor pressure of 23.8 mmHg at 25.0 degC. If this sample is placed into a 6.00L flask, what mss of liquid water will remain when equilibrium is established?
B. The standard enthalpy of vaporization (delta H vap) of carbon dis (CS2) is 28.4 kJ/mol. The normal BP of carbon disulfide is 46.3 Celsius. Calculate thevapour pressure of carbon disulfide at 13.3 Celsius. (Units:atm,torr,mmHg,pa,kPa,bar,etc)
C. The vapour pressure of a pure substance at various temperatures is presented below.
T (°C) Pvap (mmHg)
0.0 18.0
15.0 29.8
25.0 40.5
40.0 62.0
60.0 103.0
80.0 161.5
Calculate H°vap for this substance.
