Answer 2

3 atoms of oxygen are there in 4H2PO3

Step-by-step explanation:

`4H_2PO_3` exists as an anion. 4H2PO3
`4H_2PO_3` is s conjugate base of a phosphorous acid and conjugate acid of a the hydrogenphosphite.

While representing any chemical compound ,numeric value that is suffixed before atom symbol denotes the number of atoms in that particular compound. In the equation
`4H_2PO_3`, there are 4 of Hydrogen (H) atoms. Two of Phosphorus Monoxide (PO) atom. And 3 of oxygen (O) atoms.

Thus it can be concluded that there are 3 oxygen atom present in the DihydrogenPhosphate
