MIT Chem 1 exam question:
Calculate the number of fart molecules adsorbed onto your toothbrush bristles the morning after your uncle Phineas stayed over, assuming (1) he made his famous jalepeno chili cheese burgers and (2) first order reaction kinetics. The Henry's Law constant for methane is 0.0014 M/atm and the percent methane in uncle Phineas' farts is 8.32%. Ignore other gases. List any other assumptions you need to make in order to perform the calculations. Blowjobs or cocaine will also be accepted for credit on this question.
