The percent composition can be found by dividing the mass of each component by total mass. ANSWER: % (b) carbon in CS(NH2)2. ›› Ammonium Nitrate molecular weight. If the relative molecular mass of ammonium nitrate is 80, calculate the percentage of nitrogen and oxygen in ammonium nitrate. Relative formula mass (Mr): NH4NO3 = 80 Calculate the number of moles of ammonium nitrate in the bag of fertiliser. singhamanpratap0249 singhamanpratap0249 Answer: total mass is (14+4+14+3×16). The last step is to calculate the percent by mass of each element in ammonium nitrate (NH4NO3). [Relative molecular mass of ami nium nitrate is 80, H = 1, N = 14, O = 16). To calculate percent by mass, use the equation below: 15. (b) A bag of fertiliser contains 14.52 kg of ammonium nitrate (NH4NO3). The masses of the elements in one mole of the compound are: mass N = 28.0 g mass H = 4.0 g mass O = 48.0 g The molar mass of the compound is 80.0 g/mol. Calculate the percentage by mass of the indicated element in the following compounds: (a) oxygen in ammonium nitrate. NO3's percentage thus is equal to 77.5 %. The gram formula mass of ammonium nitrate is 80.04 and the gram atomic mass of nitrogen is 14.0067. Click hereto get an answer to your question ️ If the relative molecular mass of ammonium nitrate is 80, the percentage of nitrogen and oxygen in ammonium nitrate is: … Calculate the percentage of nitrogen and oxygen in ammonium nitrate. The percent composition is used to describe the percentage of each element in a compound. Molar mass of NH4NO3 = 80.04336 g/mol. Percent Composition Calculator. 61,0) (ii) … Mass percentage of oxygen in Ammonium nitrate = Number of oxygen atoms in NH4NO3 times their mass/ Molecular mass of NH4NO3*100% = (16*3/80)*100% = … The mass and atomic fraction is the ratio of one element's mass or atom to the total mass or atom of the mixture. What is the mass of one mole of the compound? Calculate the percentage of nitrogen in ammonium nitrate [ NH4NO3] [ N= 14, H = 1, O= 16] 2 See answers ameyargadeaav ameyargadeaav Answer: the total mass is 80 .
