Two planets have the same surface gravity and the same total number of gas molecules above each unit area. The air of planet X is entirely nitrogen (28 g/mol) and that of planet Y is entirely carbon dioxide . Find the ratio of the barometer reading on Y to that on X (two decimals).
Answer:
1.57
Solution:
Surface pressure = weight of the air column per unit area =
, so it is proportional to the molar mass. Ratio =
.
