Identify the chemical formula of table salt, which is sodium chloride (NaCl).
Find the atomic masses of each element from the periodic table: sodium (Na) has an atomic mass of approximately 22.99 g/mol, and chlorine (Cl) has an atomic mass of approximately 35.45 g/mol.
Add the atomic masses of sodium and chlorine to find the molar mass of NaCl using the formula: \(\text{Molar mass of NaCl} = \text{Atomic mass of Na} + \text{Atomic mass of Cl}\).
Substitute the values into the formula: \(\text{Molar mass of NaCl} = 22.99\, \text{g/mol} + 35.45\, \text{g/mol}\).
Sum the values to get the total molar mass of NaCl, which represents the mass of one mole of sodium chloride.
