The discussion revolves around calculating the pressure of interstellar hydrogen gas given its density and temperature. The Ideal Gas Law is referenced, but participants express uncertainty regarding how to determine the volume and number of moles needed for the calculation.
The conversation is ongoing, with participants exploring the implications of sample selection and representation within the gas cloud. Some guidance has been offered regarding the nature of the samples, but no consensus has been reached on how to proceed with the calculations.
Participants note the lack of additional information in the problem statement that could clarify the sample size or volume considerations.

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?
Homework Equations
Ideal-Gas Law: pV=nRT
The Attempt at a Solution
I don't know how to find the volume or number of moles for the equation.
Please help.

qspartan570 said:I don't really know.
gneill said:Is there anything in the question that would suggest that anything but a representative sample is to be considered?
qspartan570 said:No there is not anything within the question other than what is stated above.
