The number of molecules in one mole of any substance is defined by Avogadro's constant. This is a fundamental constant in chemistry and physics.

Avogadro's constant is given by the equation: $N_{A} = 6.022 \times 10^{23} {mol}^{- 1}$

Therefore, one mole contains exactly 6.02 × 10²³ molecules.

Final Answer: $6.02 \times 10^{23}$
