Homework Help: Ideal gas law qustion?

  1. Jan 28, 2009 #1
    1. The problem statement, all variables and given/known data

    Current vacuum technology can achieve a pressure of 1.0x10-6 mm of Hg. At this pressure, and at a temperature of 40.0 C, how many molecules are in 1.00cm3 ?


    2. Relevant equations[/b


    pv=nrt
    3. The attempt at a solutioni solved it using the ideal gas equation and got a very large n value,after converting from mmHg to Pa? would that be the correct procedure?

    quick few hints to doing this if your getting odd answers. a) temp needs to be converted to kelvin and b) the 1cm^3 needs to be correctly converted into m^3
