Hello! To calculate this, we should know the atomic masses of (aluminium), (sulfur) and (oxygen) atoms in some units. We can choose any units but the same for all types of atoms. Aluminium in such a molecule has the mass Thus the percent in question is so the answer is 15.8%.

Likewise, what is the percent of sulfur in aluminum sulfate? Thus, oxygen contributes about 56% of mass to aluminum sulfate. Similarly, sulfur contributes 28.1% (96/342 x 100) and aluminum contributes 15.8% to the total mass of aluminum sulfate.

In this manner, what is the percent composition of aluminum nitrate?
