Calculate the mass percent composition of nitrogen in each fertilizer: NH3, CO(NH2)2, NH4NO3, (NH4)2SO4.? 1 Answer to calculate the mass percent composition of nitrogen in each of the following nitrogen compounds NH3 Si3N4 N2H2 HCN Most fertilizers consist of nitrogen-containing compounds such as NH3,CO(NH2)2,NH4NO3, and (NH4)2SO4. Now use the concept of percent (part divided by total) to get your percent composition by mass. The gram formula mass of ammonium nitrate is 80.04 and the gram atomic mass of nitrogen is 14.0067. The nitrogen content in these compounds is needed for protein synthesis in plants. Calculate the mass percent composition of nitrogen in each of the fertilizers listed. Explanation : Given, Molar mass of C = 12 g/mole. Plants need nitrogen to grow, so many fertilizers consist of nitrogen-containing compounds. Molar Mass, Molecular Weight and Elemental Composition Calculator Enter a chemical formula to calculate its molar mass and elemental composition: Molar mass of NH3 is 17.03052 ± 0.00041 g/mol Molar mass of glucose = Now we have to calculate the mass percent composition of nitrogen … Calculate the percent composition … Mass percent composition of a molecule shows the amount each element in a molecule contributes to the total molecular mass. please explain how you get the answer. Molecular weight calculation: (14.0067 + 1.00794*4)*3 + 30.973761 + 15.9994*4 ›› Percent composition by element calculate the percent composition, by mass, of carbon in Na2CO3. You can do that now for any compound! Examples include NH3, CO(NH2)2, NH4NO3, and (NH4)2SO4. 105 L. Calculate the percent by mass of nitrogen in these fertilizers. Molar mass of N = 14 g/mole. Convert grams (NH4)3PO4 to moles or moles (NH4)3PO4 to grams. 3/17=0.18, so 18% hydrogen. Molar mass of (NH4)3PO4 = 149.086741 g/mol. Molar mass of NH3 = 17.03052 g/mol. This compound is also known as Ammonia. Calculate the mass percent composition of nitrogen in each of the fertilizers named in the problem. Molar mass of H = 1 g/mole. Answer Save Calculate the grams of nitrogen in 125 g of each fertilizer. Convert grams NH3 to moles or moles NH3 to grams. ›› NH3 molecular weight. calculate the percentage of nitrogen in NH3. 14/17=0.82, 82% nitrogen. Molecular weight calculation: 14.0067 + 1.00794*3 ›› Percent composition … First we have to calculate the molar mass of . Calculate the mass, in grams, of 20.00 mol of sodium sulfate (Na2SO4). a) 82.4% b) 35.0 %. Answer : The percent composition of nitrogen in is, 46.7 %. Nitrogen dioxide decomposes at 300°C via a second-order process to produce nitrogen 14) monoxide and oxygen according to the following chemical equation. Molar mass of O = 16 g/mole.
