At what temperature will Cl2 molecules have sufficient velocity to escape the Earth’s gravitational pull? The escape velocity from the Earth is 25,000 mph. (Note: Cl2 is diatomic, so you’ll need to double the atomic weight shown on the periodic table.)
The Attempt at a Solution
Cl=35.5g/mol Cl2≈71g/mol = 0.071kg/mol
This is where I am stuck. I don't know where to go from here. I'm not looking for an answer, just an explanation of the steps. My professor doesn't explain anything. Thank you!
