Answer: (D)

Verified step by step guidance

1. Identify the given information: the mass of the copper sample is 63.546 grams, and the atomic mass of copper is 63.546 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: \(\text{moles} = \frac{63.546\ \text{g}}{63.546\ \text{g/mol}}\).
4. Perform the division to find the number of moles of copper in the sample.
5. Interpret the result to understand how many moles correspond to the given mass of copper.
