    0.50kg of water contains 27.8 moles of water and occupies a volume of 0.00050m^3.

    Show that the volume of water vapour it produces at 100C is approximately 0.9 m^3. (atmospheric pressure is 1.01*10^5 Pa)
    I thought about using P1V1 = P2V2, but didn't know how to find P1.
    Thx for any help with this question, I'm not so good at pressures.

    edit = does this use P = p/3.<c^2> ? If so, how do I know <c^2>?
