Fe2O3(s) + CO (g) → Fe(s) + CO(g) 

a. Calculate the number of grams of CO that can react with 0.1234 kg of Fe2O3.


The flow for this problem will be like this:


kg of Fe2O(kg to g)   grams of Fe2O(molar mass of Fe2O3)  Moles of Fe2O3(mole-to-mole comparison)  Moles of CO (molar mass of CO )  Mass of CO 


Conversion kg to g : 

1 kg = 103 g
