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

• A. 65.39 g/mol
• B. 63.55 g/mol
• C. 47.87 g/mol
• D. 58.93 g/mol

Answer: (B)

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 below the element symbol on the periodic table.
4. Note that the atomic mass of copper is approximately 63.55, which means the molar mass of copper is 63.55 g/mol.
5. Confirm that this value corresponds to the correct molar mass of copper, distinguishing it from the other given options.
