How many air molecules are in a 12.0*12.0*10.0 ft room? Assume atmospheric pressure of 1.00 atm, a room temperature of 20.0 degree Celsius , and ideal behavior.

Question

How many air molecules are in a 12.0*12.0*10.0 ft  room? Assume atmospheric pressure of 1.00 atm, a room temperature of 20.0 degree Celsius , and ideal behavior.

Volume conversion:There are 28.2 liters in one cubic foot.

Dr Russ · Answer

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.
