![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)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F28c868b6-5541-4378-b4b6-f9bac704246c%2Fec9149d6-f114-4f2f-b29d-77527b7f740e%2Fmjiwa1_processed.jpeg&w=3840&q=75)
