Question

*. 6. In a gravimetric determination of P, an aqueous solution of dihydrogen
phosphate ion H2PO4^- is treated with a mixture of ammonium and magnesium
ions to precipitate magnesium ammonium phosphate, Mg(NH4)PO4.6H2O.
This is heated and decomposed to magnesium pyrophosphate, Mg2P207, which
is weighed. A solution of H2PO4^- yielded 1.054 g of Mg2P2O7. What weight of
NaH2PO4 was present originally?
(Na = 23, H=1, P=31, O=16, Mg = 24)
plzz do it by coservation of oxygen ​
