Explanation:
Detailed explanation-1: -Answer: Option A Solution: Ammonium sulphate, (NH4)2SO4 contains 21% nitrogen as ammonium cations, and 24% sulfur as sulfate anions. It is an inorganic salt which is most commonly used as a soil fertilizer.
Detailed explanation-2: -A mixture of NH4NO3 and (NH4)2HPO4 contains 30.40 % mass percent of nitrogen.
Detailed explanation-3: -→21.2% since it is (NH4)2 and thus there are two N atoms in there.
Detailed explanation-4: -In the case of ammonium sulfate this is 21–0–0. A bag of ammonium sulfate contains nitrogen, hydrogen, sulfur and oxygen in mineral form. There is no “filler” in it. Ammonium sulfate is 21 percent nitrogen.
