Please workout the problem on a piece of paper.
Equation: PV=nRT
Use the heuristic that a planet will have lost a
given molecule from its atmosphere of 4.5
Billion years if the average molecular speed
exceeds % of the planet's escape speed to
calculate what mercury's mass would have to
be in order to it to still have a nitrogen
atmosphere like earth's? The molecular
weight of nitrogen is 28 atomic units.
Evidence exists that Mars may have had oceans 0.500 km deep in its early
history. We don't know what the atmospheric pressure on Mars was back then,
but some studies suggest it may have been as high as 50,000 Pa. What would
have been the highest pressure at the bottom of these oceans? Density of water
is 1000 kg/m³, gmars = 3.71 m/s².
