A solution of methylene chloride (CHCl) and ethanol (CH3CHOH) that is 50.% methylene chloride by mass is boiling at 60.3 C. The vapor is collected and cooled until it condenses to form a new solution. Calculate the percent by mass of methylene chloride in the new solution. Here's some data you may need: methylene chloride ethanol % normal boiling point 40. C 78. C density *10 1.3 0.79 mL mL vapor pressure at 60.3 C A 1476. torr Be sure your answer has 2 significant digits. Note for advanced students: you may assume the solution and vapor above it are ideal. 372. torr ? ola Ar
