We have an ammonium compound, or rather ammonium dihydrogen orthophosphate weighing 115 grams / mol (14 (N) + 4 (H) + 2 (H) + 31 (P) + 64 (O)). 115 grams / mol of ammonium dihydrogen phosphate is 100%, and 31 grams of phosphorus is X, hence X = 26.95%. Mass fraction of phosphorus in ammonium hydrogen phosphate NH4H2PO4 = 26.95%
