Counting Moles and Atoms: Counting Moles And Atoms Worksheet

In chemistry, a mole is a unit of measurement used to quantify the amount of a substance. It is defined as the amount of substance that contains exactly 6.022 × 10 ²³elementary entities, which can be atoms, molecules, ions, or electrons.

This number is known as Avogadro’s number.

The mole concept provides a convenient way to convert between the mass and the number of particles in a sample of a substance. The molar mass of a substance is the mass of one mole of that substance. The molar mass is expressed in grams per mole (g/mol).

Relationship Between Moles and Atoms, Counting moles and atoms worksheet

The relationship between moles and atoms is given by the following equation:

number of atoms = number of moles × Avogadro’s number

For example, if you have 1 mole of carbon, you have 6.022 × 10 ²³carbon atoms.

Converting Between Moles and Atoms

To convert between moles and atoms, you can use the following steps:

1. Convert the mass of the substance to moles by dividing the mass by the molar mass.
2. Multiply the number of moles by Avogadro’s number to get the number of atoms.

For example, if you have 12 grams of carbon, you can convert it to moles by dividing by the molar mass of carbon (12 g/mol):

g ÷ 12 g/mol = 1 mol

Then, you can multiply the number of moles by Avogadro’s number to get the number of atoms:

mol × 6.022 × 10²³atoms/mol = 6.022 × 10 ²³atoms
