Encyclopaedia Britannica states that there are 602,000,000,000,000,000,000,000, or 602 followed by 21 zeroes, atoms in a mole. This number is read aloud as "602 sextillion" and is a reference to Avogadro's number, which ... More »

One mole of a compound contains Avogadro's number of molecules of that compound. Avogadro's number represents the number of atoms of carbon-12 in 12 grams of carbon-12, which is approximately 6.022 times 10^23 atoms. More »

Multiplying the total number of moles by 6.02x10^23 will give you total number of atoms present. 6.02x10^23 is known as Avogadro's Number and is the approximate number of atoms in a mole. More »

By definition, one mole is equal to the number of atoms in 12 grams of carbon-12. This is known as Avogadro's number, sometimes expressed as 6.022 x 10^23. To determine the moles in a sample of any element, you need to r... More »
