Answer : The formula unit of compound will be,

Explanation :

As we know that one atom of oxygen contains (2-) charge and one atom of lead contains (4+) charge. So, to balance the of charges of lead, the 2 oxygen atoms combine with the 1 lead atom. Thus, the compound formed will be, .

That means, when combine with oxygen that is, , it gives by the criss-cross method.

Criss cross method : It is a method of determining the chemical formula.

The formula unit is a shown below.
