It is desired to determine the molecular weight of an organic compound known to be volatile. For this, a glass balloon with a full volume of 152 mL is weighed and the weighing result is recorded as 215 g. Then, the organic compound that is desired to have some molecular weight in liquid form is added into the balloon and evaporated in a water bath until dryness. After the steam temperature is measured as 90 °C, the balloon is left to cool and the organic compound in the balloon condenses again. The balloon is then weighed again and recorded as 215,367g. Find the molecular weight of this organic compound since the pressure of the environment where the experiment is performed is 700 mmHg.
NOBr(g) decomposes to form NO and Br2 by the reaction 2 NOBr(g) → 2 NO(g) + Br₂(g) - It is found that the reaction is second order in NOB. The rate constant has been found to be 0.170 M-1 s-1. In a situation where the initial concentration of NOBr in a vessel is 0.560 M, how long will it take for the concentration of Br2 to reach 0.190 M? (Assume, of course, that there was no Br2 in the vessel to begin with.) Report your result in seconds with one decimal place but do not put units in the answer box.

Sam knows that he has one of 3 possible liquid unknowns: tetrahyrofuran (bp 65-67°C), ethyl acetate(bp 76-77°C), or toluene (bp 110-111°C). He sets up for a microscale bp determination and clamps thewhole shebang in a water bath. Fifteen minutes late the water is boiling like crazy, but he has yet tosee a single vapor bubble escape from the capillary tube. He double-checks his set-up and everythingis fine so now he’s totally confused. What must his unknown be and why? Break it to him gently…hedoesn’t want to feel like a total idiot.
Complete the following table. Calculate the vapor pressure, mm Hg, for each run. Vaporpressure, Pvapor = Pequil - Pinitial. Enter T and Pvapor from the preceding table in the following table. Complete the table by calculating the temperature in degrees Kelvin, the inverse of the temperature in degrees Kelvin, construct a graph of the natural logarithm of the measured vapor pressure,ln(Pvapor), versus1Twhere T is the average Kelvin temperature using the data from the four vapor pressure determinations.
