Mean Free Path:
The mean free path is the average distance a particle travels between collisions with other particles in a gas. Imagine throwing a ball back and forth in a room. On average, the ball will travel a significant distance between collisions before it hits something. The mean free path is the average distance between successive collisions.
Avogadro's Number:
Avogadro's number is a constant representing the number of particles in one mole of a substance. It is equal to 6.022 x 10^23. Avogadro's number tells us that there are approximately 6.022 x 10^23 particles in one mole of a substance.
Examples:
The mean free path of a gas particle is typically on the order of 10^-8 to 10^-7 meters.
Avogadro's number is a very large number, which is why it is often expressed in scientific notation
