Question

The number of particles in one mole of particles in one mole of a substance. It is a very large number equal to 6.02x10²³ particles.

A. Avogadro's number
B. Pascal's Number
C. Pythagorian's number
D. None of the above ​

Answer 1

Avogadro's number is the number of particles in one mole of a substance.

Step-by-step explanation:

The number of particles in one mole of a substance is called Avogadro's number and its value is 6.022 × 10²³.

Avogadro's number is a very large number and it is used to connect the microscopic world of atoms and molecules to the macroscopic world of grams and moles. It allows chemists to work with conveniently measurable quantities of substances.

For example, if we have one mole of water (H₂O), it contains 6.022 × 10²³ water molecules.
