Which of the following is the molar mass of aluminum (Al)?

• A. 55.85 g/mol
• B. 12.01 g/mol
• C. 35.45 g/mol
• D. 26.98 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 aluminum (Al) on the periodic table to find its atomic mass, which corresponds to its molar mass.
3. Note that the atomic mass of aluminum is approximately 26.98 atomic mass units (amu), which translates directly to 26.98 g/mol for molar mass.
4. Compare the given options to the atomic mass of aluminum to identify the correct molar mass value.
5. Confirm that 26.98 g/mol matches the atomic mass of aluminum and is therefore the correct molar mass.
