Expert Solution
Step 1

Chemical formula of phosphate ion is  PO43-  

Charge of the phosphate polyatomic ion = -3

Yes , PO43- ion has multiple resonance structures.

Moles of PO43- ion = given mass molar mass1295 mol

Number of oxygen atoms = 4 x number of phosphate ions

                                         = 4 x 1295 x Avogadro's number 

                                         = 4 x 1295 x 6.022 x 1023 

                                        = 3.04 x 1023 atoms
