Homework Help: Where to start?

  1. Apr 29, 2012 #1
    If 61022 nitrogen molecules with an rms speed of 450m=s occupy a volume of 2103 cm3, what
    is the pressure? Nitrogen molecules have a mass of 28 amu.

    I have been giving this but have no idea where to start. Can somebody point me to a starting point so i can have a go at it.

    Have you met any of the equations from the kinetic theory of gases?
    There are a couple that relate pressure of a gas to molecular speed etc.
