WebMar 19, 2024 · Complete step by step answer: The atomic number of nitrogen is 7 while the atomic mass number of nitrogen is 14. The atomic mass number also represents the … WebStep 1/1. 1) The given reaction is: 2 N 2 + O 2 → 2 N 2 O Δ H = + 82.1 k J m o l. From the balanced reaction we know that, 2 moles of N2 absorbs 82.1kJ/mol of energy. Molar mass of N2 = 28 g /mol. so, 2 × 28 g/mol of N2 absorbs 82.1kJ/mol of energy. 56g/mol of N2 absorbs 82.1kJ/mol of energy. So, 94 g of N2 will absorb heat :
