Answer:

1. What is the importance of Avogadro's number in determining the number of particles?

The reason Avogadro's number is important is that is serves as a bridge between the very large numbers and familiar, manageable units

2. What is the relationship between Avogadro's number and a mole?

A mole is a unit of measuring the amount of a substance. Avogadro’s number is the amount of atoms in one mole of a certain substance.

3. How do you find the number of particles given the mass of the sample?

Formula: number of particles = number of moles x 6 x 10

Since 1 mole of substance contains 6 x 1023 particles, 2 moles of substance contains 2 x 6 x 1023 particles.
