Why assume n = 1 mole when the question is asking for moles? If you want to use the ideal gas law, solve for n = PV/RT where P = 1 atm, V = 43.5 L, R = 0.0821 Latm/Kmol and T = 273.15 K

Thank you J.R.S for your comment. I tried to emphasize importance of conversion factors since it appears a major issue in the early stage of learning Chemistry.
