Answer:
Mass refers to the measure of number of atoms in an element or a compound. Now, since 1 mole of oxygen atoms = 16 units and every mole of oxygen contains 6.023 × 1023 atoms, Hence, 1 oxygen ion weighs = 1/6.023 × 1023 u

Explanation:
Oxygen’s atomic weight is 16.00 amu.
1 mole of oxygen is 6.02 x 1023 atoms of oxygen
1 amu = 1.661 x 10-24g
What is the molar mass (g/mole) of oxygen?
16.00 amu/oxygen atom x 1.661 x 10-24g/amu
= 2.657 x 10-24 g/atom x 6.02 x 1023 atoms/mole
=16.00 g/mole
