Answer: Use Mixture Melting Point
Explanation:
A procedure called mixture melting point would be used to determine whether or not the suspected compound is identical to the unknown.
The two suspected compounds would need to be used to create a new mixture and determine the mixtures melting point. Compare this melting points with that of the unknown compound in order to determine which one of these two suspected compounds is identical to the unknown compound.
Answer:

Explanation:
In the given molecular formula of the aluminum sulphite which is Al2(SO3)3, this molecular formula there different type of elements are bonded together to form this compound each element has a specific number of atoms present. This compound has three elements that are aluminum, sulfur, and oxygen and the atoms are present are:
Al = 2 atoms represented by subscript
S = 3 atoms represented as whole subscripts of sulfite
O = 9 atoms 3 inside bracket and 3 outside of bracket that multiplies.
Thus, total number of atoms are 2+3+9 = 14
