Answer 2

The correct answer is option D.

Step-by-step explanation:

In the given compound
`2Al_2(CO_3)_3`

In one molecule of
`Al_2(CO3_)_3` there are 9 oxygen atoms.

Then total number of oxygen atoms in two molecules of aluminum carbonate will be:

`9* 2=18 atoms`

In one
`Al_2(CO_3)_3` there are 9 atoms, then 2 molecule of aluminum carbonate there will be 18 atoms.
