Concept explainers
Interpretation:
Fertilizers given in the problem statement has to be arranged in decreasing order of mass percentage of nitrogen.
Concept Introduction:
Relative amount of the elements present in a particular compound is same always. It does not matter where the compound is obtained or prepared. Mass percentage can be calculated by simple calculation using the mass of the element present in the compound and the total mass of the compound.
