Question

1. [1 pt] What is the boiling point of compound A? Please round final answer to a whole number. Do not include units. °C

2. [1 pt] At what temperature will a solution consisting of 14 mole % A and 86 mole % B begin to boil? Please round final answer to a whole number. Do not include units. °C

3. [1 pt] Beginning at point X trace out the lines for one theoretical plate. What is the composition of the condensed vapor in mole % B? Please round final answer to a whole number. Do not include units. mole % B

4. [1 pt] When a liquid solution of unknown composition is heated until it just starts to boil the composition of the resulting condensed vapor is found to be 60 mole % A and 40 mole % B. What is the composition of the original solution in mole % B? Please round final answer to a whole number. Do not include units. mole % B

5. [1 pt] Beginning at point Y trace out the lines for two theoretical plates. What is the composition of the condensed vapor after the second theoretical plate in mole % B? Please round final answer to a whole number. Do not include units. mole % B

6. [1 pt] What is the composition (in mole fraction) of water in the vapor above a solution of water and ethanol (47 wt % ethanol) at 63.5°C? The vapor pressures of pure water and ethanol at 63.5°C are 175 torr and 400 torr, respectively. Please carry maximum number of significant figures through to final answer then round to two decimal places. Do not include units. NI water
