A solution of methyl acetate (CHO,) and water is boiling at 95.7°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.% methyl acetate by mass. Calculate the percent by mass of methyl acetate in the boiling solution.

Question

Calculate the percent by mass of methyl acetate in appointing solution around two significant digits

A solution of methyl acetate (CHO,) and water is boiling at 95.7°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.% methyl acetate by mass.
Calculate the percent by mass of methyl acetate in the boiling solution. Here's some data you may need:
vapor pressure
at 95.7 °C
normal
density
boiling point
2419. torr
0.93
mL
57. °C
methyl acetate
651. torr
1.00
mL
100. C
water
Be sure your answer has 2 significant digits.
Note for advanced students: you may assume the solution and vapor above it are ideal.
