Enthalpy of vaporization of CF2C12 at its normal boiling point of -29.2 °C is 20.25 kJ mol-1 Estimate the pressure that a can of hair spray using freon-12 had to withstand at 40 °C, the temperature of a can that has been standing in sunlight. Assume that AvapH is a constant over the temperature range involved and equal to its value at -29.2 °C.

A liquid has its vapor pressure measured at several temperatures. A graph of the ln P vs 1/T is prepared and appears below. If the equation for the line is.. y = -4699.3 k X + 2.38 What is ΔHvap for the liquid in kJ/mol? Answer should be 4 sig figs.
Calculate the boiling point of 20 grams of C6H12O6 dissolved in 350 grams of water.
A volume of 7.32 L of air is bubbled through liquid toluene at 360. K, thus reducing the mass of toluene in the beaker by 11.2 g. Assuming that the air emerging from the beaker is saturated with toluene, determine the vapor pressure of toluene at this temperature.
Calculate the total pressure in a binary system where the mole fraction of A in the vaporphase is 0.200, the vapor pressure of pure A is 100. mmHg and the vapor pressure ofpure B is 300. mmHg.
A piece of metal weighing 0.713 g was placed in an eudiometer containing aqueous HCI. After the metal fully dissolved ,23.5 mL of hydrogen gas was collected by displacement of water and a 400 mm column of water was observed. The water temperature was 25 degrees Celcius and the barometric pressure was 758.8 mm Hg ( torr). Refer to the introduction and data sheet to solve the following problems.What is the vapor pressure of the water vapor in the column? What is the pressure of the water column expressed in mm Hg (torr) ? The density of mercury is 13.6 mL.
A certain substance X condenses at a temperature of 111.6 C. But if a 200. g sample of X is prepared with 7.38 g of urea (NH2)2CO dissolved in it, the sample is found to have a condensation point of 111.9 C instead. Calculate the molal boiling point elevation constant Kb of X.
One of the detrimental effects of the "thermal pollution" of water supplies is that a rise in temperature reduces the amount of dissolved oxygen available to fish. Using the information in the table of Henry's Law constants (KH) below, calculate how many litres of water a fish requires at 30.0°C to obtain the same amount of oxygen that it could obtain from 3.05 L of water at 25.0°C.
