The formula for kinetic energy is KE=1/2(mv²). Since both mass and velocity are multiplied by each other, particle with a larger mass needs to be moving slower than a particle with less mass if both have the same kinetic energy. You can think of it as 2KE/m=v² or 2KE/v²=m, If you increase the mass the velocity needs to decrease to keep the same KE value.
I hope this helps. Let me know in the comments if anything is unclear.
Multiply .800 moles of O2 by Avagadro's number divided by 1 mole. This will get rid of the moles on the bottom and leave you with molecules. So technically .800 times 6.02x10^23.

Answer:
Dipole-dipole interactions
Step-by-step explanation:
Each molecule consists of <em>two different elements</em>.
Thus, each molecule has permanent <em>bond dipoles</em>.
The dipoles do not cancel, so the attractive forces are dipole-dipole attractions.
"Covalent bonds" is <em>wrong,</em> because there are no bonds between the two molecules.
There are dipole-induced dipole and London dispersion forces, but they are much weaker than the dipole-dipole attractions.
