You need to
1. calculate the volume of the room
2. Convert the volume to litres
3. Use PV=nRT to calculate the number of moles of gas (n). Remember to use the correct value for R and convert temperature to K.
3. multiply the number of moles (n) by Avogadros' number (6.023 x 10^23) to get the number of air molecules.
