Answer 1

★ Oxygen's atomic weight is 16.00 amu.

→ 1 mole of oxygen is 6.02 x 1023atoms of oxygen 1 amu = 1.661 x 10-24g

[Question ] What is the molar mass (g/mole) of oxygen?

Answer : Molar mass (in grams) is always equal to the atomic weight of the atom! Molar mass (in grams) is always equal to the atomic weight of the atom!
