How do I figure out how many miles of CO are needed to react with 48.5 grams of Fe2O3?

Question

how do I calculate how many miles of CO are needed to react with 48.5 grams of Fe2O3?

Answer 1

Hello C,

 

Ok now write the reaction equation

 

Fe₂O₃ + 3 CO -----> 2 Fe  + 3 CO₂

 

The number of moles of Fe₂ O₃ = (mass of Fe₂O₃)/(molecular mass)

 

                                             = (48.5g)/(2*55.85 + 3*16)

 

                                             = 0.304

 

From the reaction equation,

 

1 mole of Fe₂O₃ reacts with 3 moles of CO in a ratio of 1:3

 

The number of moles of CO that can react with 48.5g of Fe₂O₃ = 3*0.304 

 

                                                                                          = 0.912 moles
