    If we have the volume of sample of nitrogen gas that equal to 0.080 m^3 in Standard atmosphere pressure 101 pa and there is 3.6 mol from the gas then what is the temperature of the gas

    I think the law to use is :Pv=nRT .But I am not sure

    Yep, that's the correct law (generally volume is a capital V).

    So I have p =101,V=0.80,n=3.6

    And?

    Isn't the standard atmospheric pressure (approx.) 1.0 x 10^5 Pa?

    In which case you would do:

    pV = nRT

    therefore:

    T = pV/nR = (1.0 x 10^5 x 0.080)/(3.6 x 8.31)

    Plug that into your calculator, and you should get a value for the temperature in kelvin.

    (Btw you have given two different volumes, not sure which you meant but I used the first)

    Thank you and yes I meant the first volume
