Answer :
To calculate the molar mass of sodium chloride (NaCl), you need to add the atomic masses of sodium (Na) and chlorine (Cl).
Here's the step-by-step process:
1. Identify the atomic masses:
- The atomic mass of sodium (Na) is 23 g/mol.
- The atomic mass of chlorine (Cl) is 35.5 g/mol.
2. Add the atomic masses:
- Molar mass of NaCl = (atomic mass of Na) + (atomic mass of Cl)
Therefore,
[tex]\[
\text{Molar mass of NaCl} = 23 \, \text{g/mol} + 35.5 \, \text{g/mol}
\][/tex]
3. Perform the addition:
[tex]\[
23 \, \text{g/mol} + 35.5 \, \text{g/mol} = 58.5 \, \text{g/mol}
\][/tex]
Thus, the molar mass of sodium chloride (NaCl) is 58.5 g/mol.
Please note that there could have been a small typographical error in the provided numeric result (58.5 g/mol instead of the closest given option 58.4 g/mol). For your needs, you can consider the closest match, 58.4 g/mol, as the correct option from the provided choices.
