How do you find the atomic mass number of an element?
Add up the protons & neutrons in the atom
Atomic mass is the sum of the protons and neutrons in the nucleus (electrons weigh basically nothing compared to them, so they don't count)
Also you could check the periodic table, as atomic mass is usually listed. It's generally about double the atomic number (since number of protons frequently equals number of electrons).

This value can be obtained from the periodic table, where the atomic mass (or atomic weight) listed for each element is the weighted average of the masses of all naturally occurring isotopes of that element, taking into account their relative abundances. The atomic mass number of an element is found by adding together the number of protons and neutrons in the nucleus of an atom of that element. It is typically denoted by the symbol "A."

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.
