chemistry genius? A little help here.. How many moles.?

Question

iron is generally produced from iron ore through the following reaction in a blast furnace : Fe2O3(s)+ CO(g) ---> Fe(s)+CO2(g).

a. If 4.00 kg of Fe2O3 are available to react, how many moles of CO are needed?
b. How many moles of each product are formed?

Answer 1

You don't need to be chemistry genius to figure this out,

First of all, the equation must be balanced:
Fe2O3(s)+ 3 CO(g) ---> 2 Fe(s)+ 3 CO2(g).

a. With 4 kg, given sum of atomic number of 76 for Fe2CO3, there are 52.63 moles. which means 157.9 moles of CO will be needed.
b. Therefore, there will 105.3 moles of Fe and 157.9 moles of CO2.
