I have been trying to do this questions for about 30 minutes right now and its a one dot questions. I think I am converting the atoms wrong. Could someone help me? A typical region of interstellar space may contain 10^6 atoms per cubic meter (primarily hydrogen) at a temp of 100 K. What is the pressure of the gas? >Okay, what I have done was use PV=nrT, but I am having trouble converting it. Do I take the atoms and divide by avogadros? Thank You.
