SOLVED: A 12.0 g sample of KCl-KClO3 mixture is heated. KClO3 (s) decomposes by heat to KCl (s) and O2 (g). O2 (g) produced after complete decomposition occupied a volume of 1450 cm3 at 22 ºC and 1 atm pressure. What is the mass percent of KCl in the original mixture? Atomic masses (g/mol): K = 39.10, Cl = 35.5, O = 16.00(R = 0.08206 atm.L.mol─1.K─1, 0 ºC = 273 K)
