What is the molar mass of copper (Cu) in grams per mole?

• A. 28.09 g/mol
• B. 47.87 g/mol
• C. 12.01 g/mol
• D. 63.55 g/mol

Answer: (D)

Verified step by step guidance

1. Understand that the molar mass of an element is the mass of one mole of its atoms, usually expressed in grams per mole (g/mol).
2. Locate copper (Cu) on the periodic table to find its atomic mass, which is numerically equal to its molar mass in g/mol.
3. Identify the atomic mass of copper, which is typically found as a decimal number near the element symbol on the periodic table.
4. Recognize that the molar mass of copper corresponds to this atomic mass value, representing the mass of one mole of copper atoms.
5. Confirm that the molar mass of copper is approximately 63.55 g/mol, which matches the value given in the problem.
