This compound is also known as Ammonium Phosphate. Convert grams NH3 to moles or moles NH3 to grams. Each element's contribution is expressed as a percentage of the whole. Calculate the mass percent composition of nitrogen in each of the fertilizers listed. This step-by-step tutorial will show the method to determine the mass percent composition of a molecule. Molar mass of glucose = Now we have to calculate the mass percent composition of nitrogen … Answer : The percent composition of nitrogen in is, 46.7 %. calculate the percentage of nitrogen in NH3. (Atomic Mass of N=14,H=1amu) - 948754 calculate the percent composition, by mass, of carbon in Na2CO3. The gram formula mass of ammonium nitrate is 80.04 and the gram atomic mass of nitrogen is 14.0067. Molecular weight calculation: 14.0067 + 1.00794*3 ›› Percent composition … a) 82.4% b) 35.0 %. Calculate the grams of nitrogen in 125 g of each fertilizer. Mass percent composition of a molecule shows the amount each element in a molecule contributes to the total molecular mass. Molecular weight calculation: (14.0067 + 1.00794*4)*3 + 30.973761 + 15.9994*4 ›› Percent composition by element Molar mass of O = 16 g/mole. ›› NH3 molecular weight. Molar mass of (NH4)3PO4 = 149.086741 g/mol. 14/17=0.82, 82% nitrogen. This compound is also known as Ammonia. please explain how you get the answer.
