A tank holds 2.85 L of oxygen at 22.1 Celsius and 235 atm. (A) how many moles of gas does the tank contain? (B) what is the average kinetic energy per molecule ?

the answer in the text book is (a) 27.7 moles (b) 2.381x10^7pa

i just want the formula so i can attempt the problem myself so i can plug it in

I seem to recall answering this problem already. I used the fact that one mole at STP occupies 22.4 liters, and scaled for the pressure and temperature change from STP. In (B), the units of kinetic energy are not Pascals
