How many atoms are in sodium?

Finally, we convert that to the number of NaCl molecules in a mole by multiplying .45 moles by 6.02x10 23 . This equals 2.7x10 23 molecules. Because, technically, NaCl is made up of 2 atoms per molecule, you can multiply that by 2, giving 5.7x10 23 atoms. read more

In a molecule of sodium chloride, which has the chemical formula NaCl, there are two atoms: one atom each of sodium and chloride. Sodium chloride is an ionic compound formed by the reaction of the metal sodium and the nonmetal chlorine. read more

There are 1.20*10^24 atoms of sodium in 2 moles of sodium. One mole of a substance is defined by Avogadro as consisting of 6.022x10^23 atoms. This is Avogadro's number. To calculate the number of atoms in two moles of sodium, use dimensional analysis. 2.0 moles Na x (6.022*10^23g)/(1mol)=1.20*10^24 atoms of Na. read more

Sodium hydroxide has the formula NaOH and it contains three atoms, one each of Sodium, Hydrogen and Oxygen. read more

The molecular weight of sodium chloride is 58.44 grams per mole. You find this molecular weight by adding the atomic masses of sodium and chloride, which are 22.99 grams per mole and 35.45 grams per mole, respectively. read more
