(a)
Interpretation:
The formula unit formed by the combination of cation
Concept introduction:
Formula unit is the empirical formula of the ionic and covalent compound which is used in stoichiometric calculations. Formula unit for the ionic compound is the ratio of the lowest whole number. In ionic compounds, the charge of the cation is written as a subscript of the anion. On the other hand, the charge on anion is written as a subscript on the cation.
