1. Urea is (NH2)2CO with a molar mass of 60.07grams Ammonium sulfate is (NH4)2SO4....molar mass of 132.14g Urea contains 2 nitrogen atoms, that's 28g of nitrogen Ammonium sulfate also has 2 nitrogen atoms, which is also 28g of nitrogen.. Urea....28g/60.07g = 46.61% Nitrogen by mas Ammonium sulfate 28/132.14 = 21.19% Nitrogen by mass Urea is superior in % nitrogen by mass
