Which of the following is the molar mass of carbon (C)?

• A. 12.01 g/mol
• B. 6.02 g/mol
• C. 1.01 g/mol
• D. 16.00 g/mol

Answer: (A)

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. Recall that the molar mass of an element corresponds to its atomic mass found on the periodic table, which is the weighted average of all isotopes of that element.
3. Look up the atomic mass of carbon (C) on the periodic table, which is approximately 12.01 g/mol.
4. Compare the given options to the atomic mass of carbon: 6.02 g/mol, 1.01 g/mol, 16.00 g/mol, and 12.01 g/mol.
5. Identify that 12.01 g/mol matches the atomic mass of carbon, making it the correct molar mass for carbon.
