One mole of particles of any substance contains how many particles?
a. 10⁶ particles b. 6.02 × 10⁻²³ particles c. 3 × 10¹⁰ particles d. 6.02 × 10²³ particles e. 3 × 10⁻¹⁰ particles

The correct answer is Option d.

Explanation:

According to mole concept:

1 mole of a substance contains number of particles.

This number is known as Avogadro's number.

The mass of 1 mole of a substance or Avogadro number of particles has the mass equal to molar mass of that substance.

Hence, the correct answer is Option d.
