The mass of an atom (element) compared with the mass of one atom of C-12 is called:
Correct answer: D. Relative atomic mass
- A. One mole
- B. Gram atomic mass
- C. Atomic number
- D. Relative atomic mass
Explanation
The mass of an atom of an element compared with the mass of one atom of carbon-12 (C-12) is called the relative atomic mass because it provides a relative measure of the mass of an atom or element with respect to Carbon-12.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
