Homework Help: Pressure Difference Question

  1. Nov 6, 2008 #1
    1. The problem statement, all variables and given/known data
    What must the pressure difference be to raise 2 moles of gas at .001 m³ from 12 K to 276 K?

    2. Relevant equations

    3. The attempt at a solution
    P(.001 m³)=(2/6.02x10²³)(8.31)(12)

    P(.001 m³)=(2/6.02x10²³)(8.31)(276)

    Subtract the two answers to get the difference...

    What is your question?

    Why are you dividing by Avogadro's number? 'n' in your equations is the number of moles. Just sub in your values, make sure you divide by the volume to find P before you subtract the two pressures.
