Calculating masses in reactions
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.
