What will be the total vapor pressure (in torr) of a solution prepared by mixing equal masses of the two liquids?
what is the solubility of O2 at an elevation of 12,000 ft where the atmospheric pressure is 0.657 atm? Assume the temperature is 25°C, and that the mole fraction of O2 in air is 0.209 at both 12,000 ft and at sea level.
Use a combination of balanced chemical equations and their K's to calculate the equilibrium constant for the titration of formic acid with NaOH, which you used in the previous question. (Hint: You will need to include the value of Kw at some point..
