atomic number
8
chemical symbol
o
element name
oxygen
atomic mass
15.999
note: mass is grams per mole.

Explanation:

Step1: Identify the atomic mass

Look at the oxygen element box in the periodic table. The label "Atomic Mass" points to the value 15.999.

Step2: Confirm the unit

The note says the mass is in grams per mole, but the question asks for the mass value from the periodic table, so we use the given atomic mass value.

Answer:

The mass of oxygen atoms (atomic mass) on the periodic table is 15.999 grams per mole (or just 15.999 as the atomic mass value).
