Understanding the Relationship

* Avogadro's Number: One mole of any substance contains 6.022 x 10²³ particles (atoms, molecules, etc.). This is known as Avogadro's number.

Calculations

1. Set up a conversion factor: We know 1 mole of N₂ contains 6.022 x 10²³ molecules.

2. Divide the given number of molecules by Avogadro's number:

(8.37 x 10²³ molecules N₂) / (6.022 x 10²³ molecules/mole) = 1.39 moles N₂

Therefore, 8.37 x 10²³ molecules of N₂ represent 1.39 moles of N₂.
