Interpretation:
The theoretical yield of Iron sulfide formed by 83.77g of iron with an excess of sulfur needs to be determined.
Concept introduction − The theoretical yield is what would be obtained if the entire limiting reagent reacted to give the product in question.
Answer to Problem 34SSC
Theoretical yield = 155.9g.
Explanation of Solution
Given: In an experiment,
In order to convert mass of iron to moles, we need to divide mass (83.77g) by molar mass of iron (55.84g). We get 1.5 mole of iron.
Now since 2 moles of Fe produces 1 mole of
In order to convert mole of
Thus, theoretical yield = 155.9g.
