Identify the elements present in sodium chloride (NaCl), which are sodium (Na) and chlorine (Cl).
Find the molar mass of each element from the periodic table: sodium (Na) has a molar mass of approximately 23.0 g/mol, and chlorine (Cl) has a molar mass of approximately 35.5 g/mol.
Add the molar masses of sodium and chlorine to find the molar mass of sodium chloride: \(\text{Molar mass of NaCl} = 23.0\ \text{g/mol} + 35.5\ \text{g/mol}\).
Sum the values to get the total molar mass of NaCl, which represents the mass of one mole of sodium chloride.
Round the result to the nearest tenth of a gram to express the final molar mass.
