The decomposition of dinitrogen monoxide (N2O) to form nitrogen gas (N2) and oxygen gas (O2) can be represented by the balanced chemical equation: 2N2O(g) → 2N2(g) + O2(g). The molar mass of N2O is approximately 44.01 g/mol, and the molar mass of N2 is approximately 28.02 g/mol. For every 2 moles of N2O that decompose, 2 moles of N2 are formed. Given 5.54 g of N2O, we first find the moles of N2O: 5.54 g N2O * (1 mol N2O / 44.01 g N2O) = 0.1258 mol N2O. Since the reaction produces an equal number of moles of N2, we have 0.1258 mol N2. The mass of N2 formed is: 0.1258 mol N2 * (28.02 g N2 / 1 mol N2) = 3.53 g.
