4) A 11.31 g sample of a competitor's "SonicBloom" fertilizer is analyzed for its phosphorus content by gravimetric analysis through a reaction with magnesium sulfate and ammonia in water. The resulting MGNH4PO4 · 6H2O precipitate was dried and had a mass of 7.11 g. a) How many moles of phosphorus atoms are in the fertilizer sample? b) What is the weight percentage of phosphorus atoms in the fertilizer? c) What is the weight percentage of P2O5 in the fertilizer? (Or in other words, what was its middle N-P-K number?)
