WebFeb 10, 2024 · 0.740g - (0.950 - X) which is = to the mass of KCl produced by the reaction. The balanced equation shows that for every gram of KCl produced, 1.644g KClO3 is needed (formula mass KClO3/formula mass KCl), so the mass of KClO3 initially is given by 1.644 x[ 0.740 - (0950 - X) ] which is equal to X (initial mass of KClO3). WebSo to determine how many moles of oxygen atoms are present in a sample of glucose, we simply need to multiple the moles of glucose by six. So if we have 0.139 mols of glucose, we will have 0.833 mols of oxygen (0.139 x 6 = 0.834, but accounting for sig figs it becomes 0.833). Hope that helps.
