Question

An Avogadro’s number is ______.

Options

• 6.023 × 10²²

• 6.023 × 10²¹

• 6.023 × 10²³

• 6.023 × 10²⁴

Answer 1

An Avogadro’s number is 6.023 × 10²³.

Explanation:

Avogadro’s number represents the exact number of representative particles (such as atoms, molecules, or ions) present in one mole of any substance. It links the microscopic scale of atoms to the macroscopic scale of grams we can measure. For high-precision scientific work, this constant is now defined as 6.023 × 10²³.
