Answer #1

Basically, R is a universal gas constant which is independent of its atmosphere. So the value of atmosphere's R constant doesn't depend on the gas which fills the atmosphere. The value of R=8.314 m^3*Pa/mol-K*

ADDITIONAL INFORMATION

And if we want to know the atmospheric pressure,

We know that P= RT

= mass/ volume

= 2.4358*10^23/(4/3)*(22/7)*(6175000)^3

= 246.9689 kg/m^3

Temperature T = 461 K

So P= (246.9689)*(8.314)*(461) = 937199.048861 Pa = 9.2792 atm

A planet has been discovered around a Sun-like star with an estimated mass of 54.3 times the Earth\'s mass and an estimated radius of 15.1 times the Earth\'s radius. It has been hypothesized that the planet has abundant hydrogen in its atmosphere. In order for the planet to maintain a hydrogen atmosphere for a significant amount of time, the planet\'s temperature must be less than some maximum temperature. Recall that the mass of Earth is 5.97 × 1024 kg and...
