Answer:
The molecular mass (MW=molar mass) for the chemical compound, NaCl is 58.443
Step-by-step explanation:
Na being Sodium in the alkali metal group (1 valence electron) has a cumulative molecular mass of 22.990 mol., whereas Cl being Chlorine in the halogen group (7 valence electrons) has a cumulative molecular mass of 35.453. Therefore the sum of both molar masses (MW) is equivalent to 58.443 mol.
