It appears to me that you have calculate the mass of one molecule of Al(OH)3 or one formula unit. Some take that to mean the mass of 1 molecule.
1. Perhaps you want the mass of 1 mol which is about 78g.
2. Perhaps you have a problem with the number of significant figures in your answer. That often is the problem with data bases.
Calculate one Al(OH)3 formula unit in grams/unit.
I keep arriving at the answer of 1.295 x 10-22 g/unit but my homework says it is incorrect!
SOMEONE please help!!!
