A student performed the experiment described in this module, using 7.00 mL of a 1.8% H₂O₂ solution with a density of 1.01 g ml-1. The water temperature was 20 ° C, and the barometric pressure in the laboratory was 30.02 in. Hg. After the student immersed the yeast in the peroxide solution, she collected 45.1 mL of O2. (6) Calculate the mass of the H2O2 solution.
The amount of oxygen present in the blood depends in part on the partial pressure of inspired oxygen in the trachea, PIO2. This can be calculated from the barometric pressure, the fraction of O2 molecules in dry air, and the vapor pressure of water at body temperature (because inhaled air is humidified in the trachea).20.9% of the molecules in dry air are O2 molecules and the vapor pressure of water at body temperature (37 °C) is 47 mm Hg. Taking the total pressure of the humidified inhaled air to be equal to the barometric pressure, calculate the PIO2 for a person in Flagstaff, CO (elevation 2121 meters), if the prevailing barometric pressure is 576 mm Hg. PIO2 = ? mm Hg

In vacuum distillation, the surrounding pressure inside a chamber is lowered so the solvent boils at a lower temperature. This is useful when isolating compounds that are temperature-sensitive. To what pressure must a chamber be reduced to distill methanol (ΔvapH = 38.56 kJ/mol, TBP = 351 K) at 25.0°C?

From your data in Part 1 of the experiment, you calculate the natural log of the partial pressure of water and 1/T value in K for 5 points between 50°C and 80°C. You make a graph of In(P) vs. 1/T and determine that the slope of the linear line is -4800 K. Use this information to calculate AHvap of water. Make sure to use R = 8.314 J mol-1-K-1.

(a) The heat evolved upon dissolution of atmospheric ozone into water is determined to be +5 kcal/mol at 298 K. Given that ozone has a Henry’s constant of 9.4 × 10−3 mol/L/atm at 298 K, determine its Henry’s constant at 273 K. Note that the definition of Henry’s constant is for the process air to water. (b) If the atmospheric ozone concentration in a polluted air is 100 ppbv, what is the concentration in equilibrium with a body of water in that region at 298 K? Note that you need to assume no losses of ozone other than absorption into water
3. (a) At 10 °C, the vapour pressures of pure chloroform (CHCI3) and pure dichloromethane (CH2C12) are 101 mmHg and 235 mmHg, respectively. Assume that a solution made by mixing CHCI3 and CH2C12 is ideal. i. If the vapour pressure of the resulting solution is 140 mmHg and it contains 1.25 moles of components, what is the mass of CHCI3 present in that solution.
