1. The problem statement, all variables and given/known data Estimate the number N of molecules in a few grams of matter. Explain why in that case ln (N) is of the order of 50 whatever the chemical composition. 2. Relevant equations M = m/N where M is the molecular mass 3. The attempt at a solution I'm really unsure about the entire question. I have no idea what he's asking, but I might be over thinking it. I don't even know where to start.
