How to find number of atoms from moles?

Avogadro's number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal). read more

Calculate the number of molecules in 1.058 mole (or gram) of H 2 O Calculate the number of atoms in 0.750 mole (or gram) of Fe These problems use the reverse technique of the above. read more

A mole is a huge number used to measure atoms. It is equal to the number of atoms in 12 grams of carbon-12, which is approximately 6.022 x 10 23 atoms. Just as it's easier to measure intergalactic distances in light years rather than inches, it's easier to count atoms in moles than in billions or trillions. read more
