Rank the following fertilizers in decreasing order of mass percentage of nitrogen:

NH3
NH4NO3
(NH4)2HPO4
KNO3
(NH4)H2PO4
(NH4)2SO4

  • Chemistry -

    You need to work out the mass percentage of N in each. So in each case you need to the molar mass then calculate the % N content from

    Total mass of N x100%/(molar mass)

  • Chemistry -

    i worked out the mass percentage of N in each and this is what i got
    NH3=82.25%
    NH4NO3=35%
    (NH4)2HPO4=21.4%
    KNO3=13.85%
    (NH4)H2PO4=12.17%
    (NH4)2SO4=11.85%


    i put in order and still get it wrong -__-
    Total mass of N x100%/(molar mass)

  • Chemistry -

    NH3
    NH4NO3
    (NH4)2HPO4
    (NH4)2SO4
    KNO3
    (NH4)H2PO4

  • Chemistry -

    NH3
    NH4NO3
    (NH4)2HPO4
    (NH4)2SO4
    KNO3
    (NH4)H2PO4
