- How many moles of iron (Fe) are produced from 1.8 moles of iron(III)oxide (Fe2O3)?
- Using your answer from the question above, how many molecules of iron is present in
that number of moles ?
Answers
Answer:
- 3.6 moles Fe
- 2.2 x 10²⁴ molecules Fe
Explanation:
First, you need to create the balanced chemical equation.
The unbalanced equation:
Fe₂O₃ + CO -----> Fe + CO₂
Reactants: 2 iron, 4 oxygen, 1 carbon
Products: 1 iron, 2 oxygen, 1 carbon
The balanced equation:
Fe₂O₃ + 3 CO -----> 2 Fe + 3 CO₂
Reactants: 2 iron, 6 oxygen, 3 carbon
Products: 2 iron, 6 oxygen, 3 carbon
Now that we have the balanced equation, we can use the mole-to-mole ratio (from the equation coefficients) to convert from moles Fe₂O₃ to moles Fe.
1.8 moles Fe₂O₃ 2 moles Fe
-------------------------- x ---------------------- = 3.6 moles Fe
1 mole Fe₂O₃
We can convert between moles and molecules using Avogadro's Number.
Avogadro's Number:
6.022 x 10²³ molecules = 1 mole
3.6 moles Fe 6.022 x 10²³ molecules
--------------------- x ------------------------------------- = 2.2 x 10²⁴ molecules Fe
1 mole
