Extracted text: Pyrite with analysis of 85% FeS2 and 15% gangue is burned with 30% excess air (FeS2 --->SO3) 80% of the FeS2 burned was converted to SO2 and the rest to SO3 while 5% of the FeS2 charged was lost in the cinder. Cinder analysis shows 2.71% SO3. a) Determine the composition of the burner gas b) Determine the total moles of sulfur converted to SO3 c) If 80% of the SO2 was converted to SO3 in the converter, what is the final composition of the converter gas.
