A sample of air occupies 3.8 L when the pressure is 1.2 atm. What volume does it occupy at 6.6 atm? The vapor pressure of pure water at 90 ˚C is 525.8 mmHg (from Appendix G). Since the Pwater is given as 457 mmHg, the mole fraction of the water is: 457 mmHg 525.8 mmHg = 0.869 The 2.00 kg of water correspond to a mf of 0.869. This mass of water corresponds to: 2.00 x 103 g H2O • 1molH2O 18.02gH2O = 111 mol water.

Solid sodium carbonate, Na 2 CO 3, reacts with sulfuric acid, H 2 SO 4, to produce CO 2 gas according to the following equation: Na 2 CO 3(s) + H 2 SO 4(aq) → CO 2(g) + H 2 O (l) + Na 2 SO 4(aq) During an experiment to produce carbon dioxide gas, a student recorded the following data: Pressure CO 2 = 708.1 mm Hg. Volume CO 2 = 29.65 mL If you have pressure listed in mm mercury, change to atm by dividing by 760 mm/1 atm, then use R as 0.08206 L*atm/mol*K. If pressure is in kPa, use R as 8.3145 J/mol*K (kPa*L/mol*K). Pressure in mm Hg may be changed to kPa by multiplying mm Hg x 0.13332 and using R of 8.1345 BUT I've not seen that done.
