Answer:
=16.00 g/mole
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
Molar mass (in grams) is always equal to the atomic weight
