SUMMARY
To produce 44.0 grams of carbon dioxide (CO2), 135.9 grams of iron (II) dichromate (FeCr2O7) are required based on the stoichiometric relationship in the reaction 4FeCr2O7 + 8K2CO3 + O2 --> 2Fe2O3 + 8K2CrO4 + 8CO2. The molar mass of iron (II) dichromate is established as 271.85 g/mol, leading to the calculation that 0.5 moles of FeCr2O7 yield 1 mole of CO2. The discussion emphasizes the use of proportions for stoichiometric calculations, which is a preferred method among participants.
