Pressure problem

  1. Dec 7, 2011 #1
    1. The problem statement, all variables and given/known data

    Clouds of interstellar hydrogen gas have densities of up to 1.0 X 10^10 atoms/m^3 and temperatures of up to 1.0 X 10^4 K. What is the pressure in such a cloud?



    2. Relevant equations

    Ideal-Gas Law: pV=nRT



    3. The attempt at a solution

    I don't know how to find the volume or number of moles for the equation.

    Please help.

    Within the cloud is there anything to distinguish one sample volume from another?

    I don't really know.

    Is there anything in the question that would suggest that anything but a representative sample is to be considered?

    No there is not anything within the question other than what is stated above.

    So any sample of the cloud will do, right? What would be a convenient size of sample?
