Determine the number of moles of oxygen gas lost. Weight ofunknown equals 1.203 grams and weight of oxygen released equals0.391 grams. The molecular weight of oxygen gas is 32.0 g/mol.Using stoichiometry, use the number of moles of O2 gas released todetermine the number of moles of KClO3 decomposed. Determine thenumber of grams of KClO3 decomposed. The molecular weight of KClO3is 122.5g/mol. Based on the number of grams of KClO3 decomposed andthe total amount of unknown placed in the test tube, determine thepercent KClO3 present within the unknown.
