mass P2O5 = mass MgNH4PO4.6H2O x (molar mass P2O5/2*molar mass MgNH4PO4) = ?
%P2O5 = (mass P2O5)/mass sample)*100 = ?
From your mass of MgNH4PO4.6H2O collected, calculate your value
a) for the mass of "P2O5" in the initial mass of fertilizer analyzed
b) the % "P2O5" in the fertilizer. Compare this with the manufacturer's specification.
Just want to know how i would go about this question, where would I start.
