suppose your room volume is 41m^3. One mole of an ideal gas at STP occupies a volume of 22.4 L

a) estimate the number of moles of air in your room

b) how many molecules is that?

c) there are N^N ways to distribute N things onto N sites. As a rough approximation, assume there are as many states for air molecules as there are air molecules in your room. Compute the entropy of the air in your room.
