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.

WebConvert that number of moles into grams if you are asked for a mass. The calculation looks like this: 1 mol O 2 weighs 2 x 16 = 32 g. 1.60 g is 1.60/32 = 0.0500 mol. The equation says that 1 mole of oxygen is produced from 2 moles of potassium nitrate. So you must have started with 2 x 0.0500 mol KNO 3 = 0.100 mol.
