You asked: Can you give an example of a way that you use moles in your everyday life?

How are moles useful to us?

The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. However, the mole allows a chemist to work with amounts large enough to use.

What are the examples of mole?

For example, gold has an atomic weight of 196.967 amu, so one mole of gold has a mass of 196.967 grams. For a substance that is composed of more than one kind of atom, one adds up the atomic weights of the individual atoms for the chemical unit that makes up that substance.

What is mole concept example?

Moles can be used to represent a chemical reaction on a macroscopic level. For example, if a mole of water undergoes decomposition, it releases 0.5 moles of oxygen and a mole of hydrogen gas. The concept of a mole is used in determining the molarity of a substance.

How is molar mass used in everyday life?
