* Avogadro's Number: Avogadro's number (6.022 x 10^23) represents the number of particles (atoms, molecules, or in this case, tomatoes) in one mole of a substance.

* Calculation:

* Divide the given number of tomatoes by Avogadro's number:

(3.01 x 10^23 tomatoes) / (6.022 x 10^23 tomatoes/mole) = 0.5 moles of tomatoes

Therefore, there are 0.5 moles of tomatoes in 3.01 x 10^23 tomatoes.
