    If I could find it in my textbook I would have. OS is my last resort. I don't expect people to do my homework @panlac01

    I am still looking for a textbook for quick and dirty tips on chemistry to upload on my website. I think not until this fall when I get an access to mastering courses

    @rebeccaskell94 Please check this, you'll understand how it's 22.4 liters http://hyperphysics.phy-astr.gsu.edu/hbase/kinetic/idegas.html

    So If it is one molecule at N2 do I just multiply but 2 or?

    I don't think that is right. 28 is not an option

    PV = nRT;at STP:T = 273K , P = 1 atm V/n = RT/P = (0.08206 Latm/moleK) x (273K) / (1 atm) = 22.4 L/mole

    at ideal state P= 1atm v= we have to find n=1mole (given) R=0.0821 litre-atm-mol^-1 k^-1 t=273.37 K
