Organic Chemistry Lab post lab question:
In the Olympics and other major athletic competitions, a GC-MS is used to screen athletes for their use of banned substances such as steroids. If an analytical method has been developed and the retention time for a particular anabolic steroid has been determined, how might you use this method to determine the possibility of the use of anabolic steroids by an athlete?
If a sample containing 2.11 mL of nitroglycerine (density = 1.592 g/mL) is detonated, how many total moles of gas are produced?
Calculate the final temperature when a 20.4 gram sample of ice at 0oC is placed into a styrofoam cup containing 111 grams of water at 72.7 oC. Assume that there is no loss or gain of heat from the surroundings.
Using the formula W = mg, how many milliliters of water with a density of 1g/mL are required to weigh 0.75 newtons and g = 9.81 m/s2?
