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: Identify the atomic masses of sodium and chlorine The atomic masses are: - Sodium (Na) = 23 g/mol, - Chlorine (Cl) = 35.5 g/mol. Step 2: Add the atomic masses to find the molar mass of \( \text{NaCl} \) The molar mass of \( \text{NaCl} \) is the sum of the atomic masses of sodium and chlorine: \[ M_{\text{NaCl}} = 23 + 35.5 = 58.5 \, \text{g/mol} \] Answer: Therefore, the molar mass of sodium chloride (\( \text{NaCl} \)) is approximately 58 g/mol. So, the correct answer is option (1).
