Take a look at a sample calculation. Since ammonium sulfate contains only 21 percent N, other fertilizer sources more concentrated and economical to handle and transport often make a better choice for N-deficient fields. The total global demand for ammonium sulfate is approximately 24 million metric tons. Enter Your Answer As A Percentage. To get the percent composition of nitrogen is ammonium sulfate, #(NH_4)_2SO_4#, you need to know the molar mass of the compound and that of elemental nitrogen.. There is said to be about 600 grams of nitrogen in 1.00 pound of ammonium and 130 pounds of phosphorus available in 1.00 pounds of ammonium phosphate. It has a role as a fertilizer. The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs. Favorite Answer. So, the molar mass of ammonium sulfate is 132.14 g/mol and the molar mass of nitrogen … The important thing to notice is that ammonium sulfate contains 2 nitrogen atoms, each belonging to one ammonium ion, NH_4^(+). Uses. (b)percentage by weight of N in ammonium sulphate ((N H 4 ) 2 S O 4 )- Weight of nitrogen = 1 4 g Weight of nitrogen in ( ( N H 4 ) 2 S O 4 ) = 2 × 1 4 = 2 8 g Question: What Is The Percent Composition Of Nitrogen In Ammonium Sulfate, A Common Fertilizer? Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia.A high-melting (decomposes above 280℃) white solid which is very soluble in water (70.6 g/100 g water at 0℃; 103.8 g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils. Ammonium sulfate, (NH 4) 2 SO 4, is an important ingredient in many artificial fertilisers supplying to plants the essential mineral elements of nitrogen and sulfur. (a) Calculate the percentage of nitrogen and the percentage of sulfur in ammonium sulfate. The percentage of nitrogen in ammonium sulfate is 10.6 %. You can write the percent composition of nitrogen in ammonium sulfate by dividing the molar mass of the two nitrogen atoms by the molar mass of the compound, and multiplying the result by 100. So For Instance If It Is 50%, Enter 50 Don't Add The Percentage Sign And Don't Use Decimal. Fertilizers supply the essential elements, nitrogen, phosphorus and potassium for plant growth. Ammonium sulfate has increasingly replaced ammonium nitrate as a synthetic nitrogen source for fertilizer since 2004. To get the percent composition of nitrogen is ammonium sulfate, #(NH_4)_2SO_4#, you need to know the molar mass of the compound and that of elemental nitrogen. Ammonium Sulfate. The primary use of ammonium sulfate is as a fertilizer for alkaline soils.In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. A number that is still growing and of which 10% is produced, distributed and supplied by Fibrant. formula mass of ammonium sulfate … However, it provides an excellent source of S, which supports or drives numerous … A bag of fertilizer contains 500g of ammonium sulfate, $ \small \ce{(NH4)2 SO4}$, and 500g of potassium nitrate, $\small \ce{KNO3}$. Enter Your Answer As A Percentage. The important thing to notice is that ammonium sulfate contains 2 nitrogen atoms, each belonging to one ammonium ion, #NH_4^(+)#.. Explanation: The chemical formula of ammonium sulfate is . Ammonium Sulfate is a solid, crystalline salt that is mainly used as a fertilizer, providing both nitrogen and sulfur for crop production. Calculate the percentage by mass of nitrogen in the bag of fertilizer. 1 mole of ammonium sulfate contains 1 mole of nitrogen atom, 4 moles of hydrogen atom, 2 moles of sulfur atom and 8 moles of oxygen atom.
