How Many Moles Of Iron Oxide Is Required To Produce 10 Moles Of Carbon Diox

how many moles of iron oxide is required to produce 10 moles of carbon dioxide in the reaction 2Fe2O3 + c= Fe + 3CO2

Solution

Let’s just take this step by step.

Step 1: Understand the vocabulary. Mol is 6.022 x 1023 pieces of a substance or molecule. It is similar in concept to a dozen.

Step 2: Look at the equation and mark what you need. Remember Iron Oxide is Fe2O3 and Carbon Dioxide is CO2.

2Fe2O3 + C= Fe + 3CO2 This is what the reaction is giving you but you need 10 mols (60.22 x 1023)

So: if 2 Iron Oxides = 3 Carbon dioxides, then 2 mols of iron oxide = 3 mols of carbon dioxide.

Step 3: Set up an equivalency and solve.

2 Fe2O3 =. x.

3 CO2 10 CO2

So, 2 x 10 = 20/3 = 6 and 2/3 mols.
