How does the number of molecules in 1 mol of oxigen compare with the number of molecules in 1 mol of nitrogen?

They are the same.

Explanation:

Hello!

In this case, according to the Avogadro's number, we take into account that for molecules such as gaseous oxygen (O₂) and nitrogen (N₂), we realize that 1 mole of these contain 6.022x10²³ moles of molecules; as we are given  1 mol each, we notice they both have 6.022x10²³ molecules, therefore, they number of molecules is the same because they have the same number of moles.

Best regards!

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
