We are asked to calculate for the percent by mass (mass %) of each element in Al(OH)3 and to do that we’re going to use the mass percent formula shown below:

First, we need to get the atomic weights of each element in Al(OH)3 using the periodic table and then calculate its molar mass.

Mass of Al:
