Question

_____________________ is the number times one atom of an element is heavier than $1/12$ the mass of an atom of carbon ($C^{12}$).

• A. Relative atomic mass
• B. Relative molecular mass
• C. Gram atomic mass
• D. Gram molecular mass

Answer 1

The correct option is A Relative atomic mass

The ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon - 12 is called relative atomic mass.

RAM = $\frac{\text{M}assofoneatomoftheelement}{1/12Massofoneatomofcarbon\left[C^{12}\right]}$
