Help on RMS question

  1. Mar 17, 2007 #1

    Im having trouble answering this question.

    If the density of nitrogen at STP (1.01 X 10^5 Pa and 0 degrees celsius) is 1.25kgm^-3, calculate the RMS speed of nitrogen at 227 degrees celsius.

    Could someone please point me in the right direction?

    Thank you.
