Question

What is the molar mass of \( \text{NaCl} \)?

• A. 58 g/mol
• B. 60 g/mol
• C. 62 g/mol
• D. 56 g/mol

Hint:

Remember: The molar mass of a compound is the sum of the atomic masses of its constituent elements.

Answer 1

The Correct Option is A

Step 1: Determine atomic masses Atomic masses: Sodium (Na) = 23 g/mol, Chlorine (Cl) = 35.5 g/mol.Step 2: Calculate molar mass of \( \text{NaCl} \) Molar mass of \( \text{NaCl} \) = sum of atomic masses of sodium and chlorine:\[M_{\text{NaCl}} = 23 + 35.5 = 58.5 \, \text{g/mol}\]Answer: The molar mass of sodium chloride (\( \text{NaCl} \)) is approximately 58 g/mol. This corresponds to option (1).
