Q2) 90 proof bourbon is 45% ethanol (CH,CH2OH). Determine each of the following for this material. You may need to know that the density of this bourbon is 0.9227 g/ml (1), pure ethanol is 0.7893 g/mL (2), and water (assume the rest is just water) is 1.00 g/mL. a) What is the mole fraction ethanol? b) What is the molarity of the ethanol? c) What is the molality of the ethanol? Q3) Exercise #23 from your text has CO2 in a drink at 0.10 M concentration but only under high pressure. When you open a can, the pressure drops to 1.0 atm. How much (moles) CO, is released from the can when it is opened? [Note: think about how #23 was solved and then do that again for the changed question here. The difference should give you your answer..] Q4) Assuming ideal solution behavior, what is the boiling point of a solution of the sugar solution in Q1 above? [You will need table 11.2 from the text for this)
