Web13 dec. 2024 · First, we convert grams of Kcl into moles by dividing by its molar mass: (15.0 g KCl) x (1 moles/74.55g) = 0.201 moles KCl. Then, we convert moles of KCl to moles of O2 using the molar ratio from the balanced equation: 0.201 moles KCl x (3 moles O2/2 moles KCl) = 0.302 moles O2. Finally, we convert moles of O2 to grams of O2 by … northern song dynasty wikipedia
