A solution of acetic acid CH3COOH and water is boiling at 100.4°C . A sample of the vapor above the solution is cooled until it condenses. This condensed sample is analyzed, and turns out to be 10.% acetic acid by mass. Calculate the percent by mass of acetic acid in the boiling solution. Here's some data you may need: normal boiling point density vapor pressure at 100.4°C acetic acid 118.°C 1.1gmL 538.torr water 100.°C 1.00gmL 771.torr Be sure your answer has 2 significant digits. Note for advanced students: you may assume the solution and vapor above it are ideal.
