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. x10 wwww.m w. ?

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
