How many molecules are in one mole of a substance?

Back

One mole of any substance contains approximately 6.022 x 10^23 molecules, known as Avogadro's number.

Front

How do you calculate the number of molecules from moles?

Back

To calculate the number of molecules from moles, use the formula: Number of molecules = Moles x Avogadro's number (6.022 x 10^23).

How do you find the mass of a sample given the number of atoms?

Back

To find the mass of a sample given the number of atoms, first convert atoms to moles using: Moles = Number of atoms / Avogadro's number, then use: Mass (g) = Moles x Molar Mass (g/mol).
