How many moles of sulfur are needed to obtain 6.00 moles of [tex]\text{Fe}_2\text{S}_3[/tex]?

Answer :

Answer:

You would need 9.00 moles of sulfur to obtain 6.00 moles of Fe2S3.

Explanation:

The balanced chemical equation for the formation of iron(III) sulfide (Fe2S3) is:

4 Fe + 3 S -> 2 Fe2S3

The equation shows that it takes 3 moles of sulfur (S) to produce 2 moles of Fe2S3.

So, to obtain 6.00 moles of Fe2S3, you would need:

(6.00 moles Fe2S3 / 2 moles Fe2S3) * 3 moles S = 9.00 moles of sulfur (S)

Therefore, you would need 9.00 moles of sulfur to obtain 6.00 moles of Fe2S3.

Final answer:

To obtain 6.00 moles of Fe2S3, you would need 9.00 moles of sulfur.

Explanation:

To find the number of moles of sulfur needed to obtain 6.00 moles of Fe2S3, we need to use the balanced equation for the reaction:

FeS + 1.5 S → Fe2S3

From the equation, we can see that 1 mole of Fe2S3 contains 1.5 moles of sulfur. Therefore, to obtain 6.00 moles of Fe2S3, we would need:

6.00 moles Fe2S3 * 1.5 moles S / 1 mole Fe2S3 = 9.00 moles of sulfur.
