124,60 grams of Fe3(PO4)2 are equal to 0,35 moles.
Be3(PO4)2--------------Beryllium phosphate
If you think to the molar mass this is 601,9237 g.
Barium is in Group 2, so we know that it makes 2+ ions. If you happen to have a chart of common polyatomic ions, you can find out that phosphate is PO4 and has a 3- charge. So, to even out the charges, we need to get three barium ions and two phosphate ions. Now, the total positive charge (from the barium ions) is 6+, and the total negative charge (from the phosphate ions) is 6-.We see that Ba3(PO4)2 is the chemical formula for barium phosphate.
Fe3(PO4)2 Ferrous Phosphate or, the more modern name; Iron(II)phosphate
The molar mass of Pb3(PO4)2 is 811,54 g.

Fe3(PO4)2
Fe3+ combines with PO43- ion to form FePO4 FePO4 is called ferric phosphate or iron(III) phosphate
Formula: Fe3(PO4)2
FeBr2 + H3PO4 <--> Fe3(PO4)2 + HBr
FeSO4 + K3PO4 ---> Fe3(PO4)2 + K2SO4
The chemical formula of ferrous phosphate is Fe3(PO4)2.
T he correct formula for iron(III) phosphate is Fe3(PO4)2.
45.3g/Mmass phosphate x 4mol PO4/1mol x molar mass of ammonium phosphate
