1. Estimate the number of oxygen molecules in LTD under normal pressure and temperature.
2. I'm guessing you use PV=nRT to get the number of moles of gas in the room and work out the % of oxygen in the air, but I got a number which to me looks too small.
3. Volume of LTD is approx 200m^3, P=101325 Pa, R=8.314472 J K-1 mol-1, T=273.15 K.
n=8922.996613.
20.95% of air is oxygen, therefore I wound up with 1869.36779 molecules of oxygen in the room.
(See I can't tell if there is more to it, or if the holidays have turned me into a thoroughbred moron)
