Calculate the mass of CO needed to react completely with 50.Og of Fe2 03?
We must first create a balanced equation. Carbon monoxide is commonly used in industry to liberate iron from its oxides (which are often found in rock). This produced Carbon dioxide and solid iron.
Now we must find how many moles 50.0 g of Iron (III) oxide corresponds to:
Using the equation:
Now from the molar ratios we can see that we require 3 moles of
Then using the same equation we can find the mass of
