Al(ClO2)3 - AlCl3 3O2 use molar mass to find moles Al: 75.0 grams 229.34 g/mol 0.3270 moles of Al(ClO2)3 using the equation: Al(ClO2)3 - AlCl3 3O2 0.3270 moles of Al(ClO2)3 produces 3 X's as many moles of O2+ 0.981 moles of O2 find litres+ PV nRT (670Torr)V 0.981 mol (62.4 Torr-Litres/mol-K)(298Kelvin) V 27.23 litres which in this 3 sig fig problem rounds off to: your answer 27.2 litres of oxygen
