Avogadro’s number is the number of molecules present in gram molecular mass

Explanation:

Avogadro's number, 6.022 × 10²³, represents the number of molecules (or atoms, ions, or particles) present in one mole of a substance.

The gram molecular mass (or molar mass) of a substance, measured in grams, contains exactly 6.022 × 10²³ molecules or entities, making the statement true.
