Answer: (B)

Verified step by step guidance

1. Identify the given information: mass of iron (Fe) is 82.5 grams, and the molar mass of Fe is 55.85 g/mol.
2. Recall the formula to calculate moles from mass: \(\text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}}\).
3. Substitute the given values into the formula: \(\text{moles} = \frac{82.5}{55.85}\).
4. Perform the division to find the number of moles of iron present.
5. Compare your calculated value with the provided options to select the correct number of moles.
