(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Calculate the thickness of Earth's atmosphere.

Assume that the pressure and temperature do not vary with height.

Make reasonable assumptions for their values.

2. Relevant equations

I think this question has to be solve with ideal gas equation which is PV=nRT

3. The attempt at a solution

Since the problem stated that the pressure and temperature do not vary with height,

so I assume it is stp which pressure is 1atm, and 25^{。c}(I suppose the absolute temperature for ideal gas law to be 273 K, but it seems to be impractical and not consistent with the problem).

then i stuck, i do not know how to obtain the value for n.
