12 mole KCIO3 x 3/2= 18 molesO2
number 3:
Moles of Cl2 = 1.0 /71 g/mole= .014 moels x 2/1 = .028 moles x 74.5 g/mol = 2.09 grams
number 4:
Moles of Na2O = 120 g/ 62 g/mol = 1.93 mole x 2/1 = 3.86 moles x 40 g/mol= 154.4 grams NaOH
number 5:
Moles of S8 = 16.0 g/ 256 g/mol= .062 moles x 8/1= .496 moles x 56 g/ mol = 28 g Fe
