When heated, kclo3 decomposes into kcl and o2. if this reaction produced 88.4 g of kcl, how much o2 was produced (in grams)? > 2kcl+3o_2 2(kclo_3)=245.096 , 2kcl=149.102g, 3o_2=95.994

In this decomposition reaction, we are given with the mass of KCl and the amount of oxygen gas to be produced is asked. The stoichiometric ratio of KCl to O2 is 2:3. Given the mass of KCl, we convert this to moles by dividing the given mass by its molecular weight, 74.55 g/mol equal to 1.1858 mol. As to the stoichiometry of the reaction, multiply 1.1858 by 3 and divide by 2 to get the moles of O2, which is equal to 1.78 mol or 56.92 grams oxygen.
