How many mol of sodium corresponds to 1.0 x 10^15 atoms of sodium?

The moles of sodium are .

Explanation:

Moles of sodium = n

Number of atoms of sodium , N =

Where , atoms/ molecules (Avogadro number)

n =

The moles of sodium are .

screening

explanation:

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
