WebFrom the mole ratio in the balanced chemical equation: 1 mol AgCl (B) 0.0125 mol KCl x = 0.0125 mol AgCl formed 1 mol KCl Then convert to grams of AgCl: 143.4 g AgCl (C) 0.0125 mol AgCl x = 1.79 g AgCl formed mol AgCl … WebSo, for 0.375 mol of KO2, we can set up a proportion: 4 mol KO2 / 3 mol O2 = 0.375 mol KO2 / x mol O2 Solving for x, we get: x = (3 mol O2) (0.375 mol KO2 / 4 mol KO2) = 0.28125 mol O2 Therefore, 0.375 mol of KO2 produces 0.28125 mol of O2. Step 2/3 Next, we need to use stoichiometry to find the amount of CO2 used to produce 8.5 g of O2.
