What is \rm? This same notation shows up almost every day and most of us don't have a clue as to its meaning.
From what I can tell, \rm shows up when a question is cut and pasted from Mastering Chemistry, the online homework program. It must have to do with programming language because it doesn't show up in the original problem. It can be ignored for the sake of solving it.
