Answer:
approximately 106 grams
Explanation:
The molecular mass of Aluminum Oxide is approximately 102 grams per mole.
2×Al=
2×27=54
3×O=3×16=48
54+48=102
200
102
=1.96 moles
There are two atoms of Aluminum in one mole and each atom has a mass of approximately 27 grams so
Mass of Al = 1.96×2×27=106 grams
