A solution of methylene chloride (CH₂Cl₂) and ethanol (CH₂CH₂OH) 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 0% normal boiling point 40. °C 78. °C density X 1.3 mL 0.79 8 mL vapor pressure at 60.3 °C Be sure your answer has 2 significant digits. Note for advanced students: you may assume the solution and vapor above it are ideal. S 1476. torr 372. torr
