How many grams of co are needed to react with an excess of fe₂o₃ to produce 156.2 g fe? show your workfe2o3 (s) + 3 co (g) --> 3 co2 (g) + 2 fe (s) - 20

moles Fe = 209.7 g/ 55.847 g/mol=3.75  

the ratio between Fe and CO is 2 : 3  

moles CO = 3.75 x 3 /2 =5.63  

mass CO = 5.63 mol x 28.01 g/mol=157.7 g
