What is the molar mass of sodium chloride (NaCl)?

• A. 35.45 g/mol
• B. 22.99 g/mol
• C. 58.44 g/mol
• D. 74.55 g/mol

Answer: (C)

Verified step by step guidance

1. Identify the elements present in sodium chloride (NaCl), which are sodium (Na) and chlorine (Cl).
2. 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.
3. Add the atomic masses of sodium and chlorine to find the molar mass of sodium chloride using the formula: \(\text{Molar mass of NaCl} = \text{Atomic mass of Na} + \text{Atomic mass of Cl}\).
4. Substitute the values into the formula: \(\text{Molar mass of NaCl} = 22.99\ \text{g/mol} + 35.45\ \text{g/mol}\).
5. Sum the values to get the total molar mass of sodium chloride.
