The relative atomic mass of an element is?

A. the mass of only the neutrons in the atom's nucleus.
B. the mass of its atoms compared to the mass of a carbon-12 atom.
C. the mass of its isotopes compared to the mass of a normal atom.
D. the mass of its atoms averaged over time.

Answer 1

Well I would go for #B#....

The relative atomic mass is the WEIGHTED AVERAGE of the isotopes compared to the mass of a #""^12C# isotope... And given this definition, #B# is the probable answer...

How many neutrons, and how many protons, and how many electrons are present in a single #""^12C# ATOM, and how do you know?

The relative atomic mass of an element is the weighted average mass of the atoms of that element compared to the mass of an atom of carbon-12. It is usually expressed in atomic mass units (u) or grams per mole (g/mol).

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
