Answer: (C)

Verified step by step guidance

1. Identify the given information: mass of NaCl = 25.0 grams, molar mass of NaCl = 58.44 g/mol.
2. Recall the formula to convert grams to moles: \(\text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}}\).
3. Substitute the given values into the formula: \(\text{moles} = \frac{25.0}{58.44}\).
4. Perform the division to find the number of moles (do not calculate the final value here, just set up the expression).
5. Compare the calculated moles with the provided options to determine which is correct.
