Chapter 3: Problem 26

What is a mole? How is a mole related to Avogadro's number?

Short Answer

Expert verified
A mole is the system international unit for the amount of a substance and is defined as containing exactly \(6.02214076 × 10^{23}\) elementary particles, this number is known as Avogadro's number. Hence, a mole is related to Avogadro's number as it contains Avogadro's number of particles.

Step by step solution

01

Define a Mole

In chemistry, a mole is the system international unit for the amount of a substance. It is defined as exactly \(6.02214076 × 10^{23}\) elementary particles (this can be atoms, molecules, ions, etc.) This number is also known as Avogadro's number.
02

Relationship between a Mole and Avogadro's Number

A mole of any substance contains Avogadro's number of elementary particles. For example, one mole of carbon-12 atoms contains \(6.02214076 × 10^{23}\) carbon atoms. This is how Avogadro's number relates to a mole; it is the number of particles comprising a mole.
03

Practical Implications

The concept of the mole is used as a bridge between the atomic and macroscopic world. It allows chemists to count atoms by weighing. It indicates that if you weigh a substance in grams equivalent to its atomic or molecular weight, you have Avogadro's number of such atoms or molecules.
