A solution of methyl acetate C3H6O2 and water is boiling at 98.4°C. A sample of the vapor above the solution is cooled until it condenses. This condensed sample is analyzed, and turns out to be 25.% methyl acetate by mass.
Calculate the percent by mass of methyl acetate in the boiling solution. Here's some data you may need:
| normal boiling point | density | vapor pressure at
98.4°C |
|
| methyl acetate |
57.°C |
0.93gmL |
2603.torr |
| water |
100.°C |
1.00gmL |
719.torr |
Be sure your answer has the correct number of significant digits.
Note for advanced students: you may assume the solution and vapor above it are ideal.

Calculate the % Al in the sample. Preparation of a stock solution of aluminum. Accurately weigh out approximately 1 g of the aluminum foil. Tear it up into small pieces, place the pieces into a covered 250 mL beaker and add 60 mL of 6M HCl. This should be carried out in the fume hood because the reaction is exothermic and leads to violent frothing and emission of vapors. Cool, quantitatively transfer to a 250 mL flask, rinsing with deionized...
