Answer:
1.69*10^{22} number of ions.
Explanation:
Since we know that the gram molar mass of the compound Na2HPO4 is
141,96 g/mol so the number of moles for 1 gram of the above compound will be 1/141,96 which will be =0.007 moles.
So, we know that for the compund we have the number of molecules to be Na2HPO4=0.007 moles*6.02*10^{23}=4.214*10^{21}molecules where 6.02*10^{23} is the Avogadro's number.
As, we know that the equation is Na2HPO4 - > 2Na+ + H+ + (PO4)3- hence we can find the total number of ions as :-
The total number of ions will be =4.214*10^{21}*4 = 1.69*10^{22}.
