1. (A) (2.85/22.4)* 235*(273.2/295.3) moles
(B) (3/2)kT
k is the Boltzmann constant.
If you include kinetic energy of O2 molecule rotation, the answer is (5/2) kT

2. but 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

3. My answer to (A) agrees with the text book.
The answer to (B) cannot be in Pascals. You mistyped something or the book is wrong. I gave you the formula.
