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!!!
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.
