WebThe balanced chemical equation for the reaction is: 2 ZnO → 2 Zn + O2. From the equation, we can see that 1 mole of ZnO decomposes to produce 1 mole of O2. The molar mass of ZnO is 81.39 g/mol. Therefore, the number of moles of ZnO present in 1.226 g is: moles of ZnO = 1.226 g / 81.39 g/mol = 0.01506 mol. So, 0.01506 moles of O2 are formed. WebJun 23, 2024 · Solution. We will simply follow the steps. mass K → mol K → mol Mg → mass Mg. In addition to the balanced chemical equation, we need the molar masses of K (39.09 g/mol) and Mg (24.31 g/mol). In one line, 86.4 g K × 1 m o l K 39.09 g K × 1 m o l M g 2 m o l K × 24.31 g M g 1 m o l M g = 26.87 g M g. Exercise 5.5. 3.
