A solution of carbon tetrachloride and acetic acid CH3COOH is boiling at 107.6°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.% carbon tetrachloride by mass. Calculate the percent by mass of carbon tetrachloride in the boiling solution. Here's some data you may need: normal boiling point density vapor pressure at 107.6°C carbon tetrachloride 77.°C 1.6gmL 1733.torr acetic acid 118.°C 1.1gmL 623.torr Be sure your...
