Explanation:

Step1: Recall molar mass of sodium

Sodium (Na) has an atomic mass of approximately 22.99 g/mol (from periodic table). Molar mass of an element is numerically equal to its atomic mass (in atomic mass units) and has units g/mol.

Step2: State the molar mass

So, molar mass of sodium is 22.99 g/mol (or sometimes rounded to 23.0 g/mol, but exact value from periodic table is ~22.99 g/mol).

Answer:

22.99 g/mol (or 23.0 g/mol, depending on precision; the exact molar mass of sodium is approximately 22.99 g/mol)
