- Homework Statement
- Interstellar gas consists of a mixture of H and He molecules (10^4) and (10^3) respectively (in a 1m^3 volume). What is the pressure of the gas if the temperature is 80K?

- Relevant Equations
- PV = nRT

n = 11000 because n = N/V and V = 1m^3.

Using P = nRT/V I get that P = 7.32x10^6 Pa.

considering that the gas is in a high vacuum, this value seems far too high to be true.

Please help?
