Question: the h2 he molecular ratio for neptune is approximately...
The H2 : He molecular ratio for Neptune is approximately 4.0 :
1.0, and other gases are so rare that they can be ignored. Assuming
that the relative molecular mass of H2 is 2.0 and He is 4.0,
calculate the following. i.The average relative molecular mass .
ii.Average mass in kg of a molecule in Neptune’s atmosphere. Show
your working in each case.
The density of Neptune’s atmosphere at 1.0 bar is 0.45 kg m−3. Assuming that Neptune’s atmosphere behaves as an ideal gas, calculate the temperature at the 1 bar level using the equation T = (Pm) / (1.38*10^-23)p. Show your working, including the derivation of units for your final answer.
T = (Pm) / (1.38*10^-23)p
