Begin by finding the mass of the NaCl molecule.
Na=22.99
Cl=35.45
NaCl=58.44
Now divide the mass of sodium by the mass of the molecule to determine the percent of sodium.
22.9958.44=0.3933
Na=39.33%ofNaCl
Na=22.99
Cl=35.45
NaCl=58.44
Now divide the mass of sodium by the mass of the molecule to determine the percent of sodium.
22.9958.44=0.3933
Na=39.33%ofNaCl
