Hey Mao,


The precipitate was filtered, washed and then converted by heating into Mg2P2O7


I wasn't so sure, about this whole process. But, if its simply converted, wouldn't the mols remain the same? I also used

MgNH... as it was in a solution...whilst the latter Mg2P2O7m is dried and stuff, hence perhaps isn't compatible with the question?

): I've got no solutions Haha atm haha xD.

The equation for thermal decomposition of magnesium ammonium phosphate n-hydrate is



The ionic equation is



Thus n(P) = n(MgNH4PO4) = 2 n(Mg2P2O7)
