What is the atomic mass of carbon dioxide?

Answer 1

Atomic mass is very simple to calculate. Since carbon dioxide has the structure #CO_2# There is one carbon and 2 oxygen so you look to the periodic table to find the atomic mass, which is located under the symbol and name of the element on the periodic table. Carbon atomic mass of 12 amu Oxygen atomic mass of 16 amu

You compute it as follows since there are one carbon and two oxygen atoms:

1(12) + 2(16) = 44

One carbon atom plus two oxygen atoms add up to the atomic mass of carbon dioxide, which is roughly 44.01 atomic mass units (u).

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.
