A particular plant food has a label that reads 8-12-4. The second number refers to the % P2O5 the plant food contains. Gravimetric analysis was done on a 10.0 g sample of plant food and you removed the phosphorus according to the equation below: 5H20(l) + HPO42- (aq)+ NH4+(aq) +Mg2+(aq)+OH-(aq) __> MgNH4PO4 . 6 H2O(s) If you obtain 4.75 g of precipitate, Calculate the experimaental % P2O5 . Is it close to the label reading of 12%?
