58.44g/mol

Explanation:</h2>
Required:
Mass of sodium chloride (NaCl)
From the periodic table, it is known that the mass of;
Sodium (Na) = 22.99g/mol
Chlorine (Cl) = 35.45g/mol
From NaCl, there are:
1 atom of sodium and;
1 atom of chlorine.
Therefore, to get the molar mass, or simply mass, of sodium chloride (NaCl), (i) multiply the mass of sodium (22.99g/mol) with the number of atoms (1) in the NaCl. i.e
22.99g/mol x 1 = 22.99g/mol
(ii) multiply the mass of chlorin (35.45g/mol) with the number of atoms (1) in the NaCl. i.e
35.45g/mol x 1 = 35.45g/mol
(iii) add the results in (i) and (ii) together. i.e
22.99 + 35.45 = 58.44g/mol
In essence, the molar mass of Sodium chloride is the sum of the molar masses of the atoms of sodium and chlorine. This is 58.44g/mol
