Expert Solution

Explanation of Solution

Given chemical formulas are Al(C2H3O2)3 and Ba(H2PO4)2.

Total number of atoms in Al(C2H3O2)3: This contains one aluminium atom, six carbon atoms, nine oxygen atoms and six oxygen atoms in its chemical formula. Therefore, a total of twenty two atoms are present in the chemical formula.

Total number of atoms in Ba(H2PO4)2: This contains one barium atom, four hydrogen atoms, two phosphorus atoms, and eight oxygen atoms in its chemical formula. Therefore, a total of fifteen atoms are present in the chemical formula.

On comparing the total number of atoms between the two chemical formulas, it is found that Al(C2H3O2)3 contain more number of atoms than Ba(H2PO4)2.
