A solution of acetic acid (CH₂COOH) and water is boiling at 103.1 °C. A sample of the vapor above the solution is cooled until it condenses. This condensed sample is analyzed, and turns out to be 50.% acetic acid by mass. Calculate the percent by mass of acetic acid in the boiling solution. Here's some data you may need: acetic acid water % normal boiling point 118. °C 100. °C density 1.1 1.00 g mL mL vapor pressure at 103.1 °C 568. torr 846. torr Be sure your answer has the correct number of significant digits. Note for advanced students: you may assume the solution and vapor above it are ideal.
