The number of carbon atoms that are present in a mole of 12 C is 6.022 x 10²³
What are moles?
The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
Mole = Number of 12C atoms in exactly 12 g of 12 C.
6.022 x 10²³ is the Avogadro number. The quantity of moles is equal to the exact number of atoms in grams.
This is the theoretical atomic mass it contains, 6 protons and 6 neutrons. The carbon 12 of isotopes. One mole of carbon will contain exact 6.022 x 10²³ moles.
In 12 g of 12 C there are 6.022 x 10²³ atoms 12 C.
1 mole = 6.022 x 10²³
12 g of 12C contains 6.022 x 10²³ carbon atoms or 1 mol of carbon atoms.
Thus, the number of carbon atoms in a mole of 12 C is 6.022 x 10²³.
