A student carries out the following reaction: 2 Fe (s) + 3 S (g) → Fe,S3 (s). The student determines that 0.32 moles of iron (III) sulfide were produced, resulting in a 76% yield. How could the student determine the initial amount of sulfur used? O A Convert moles of iron (III) sulfide to moles of sulfur using the mole ratio of 1 mole Fe,S3 mole S. O B. Convert moles of iron (III) sulfide to moles of sulfur using the mole ratio of 3 mole Fe,S:1 mole S. O C. Determine the moles of iron (III) sulfide if 100 percent were reacted by placing 76% equal to 0.32 moles/x and then converting moles iron (III) sulfide to moles of sulfur using the mole rati of 3:1. O D. Detemine the moles of iron (III) sulfide if 100 percent were reacted by placing 24% equal to 0.32 moles/x and then convert moles of iron (III) sulfide to moles of sulfur using the mole ratio of 3:1.

A student carries out the following reaction: 2 Fe (s) + 3 S (g) → Fe,S, (s).
The student determines that 0.32 moles of iron (III) sulfide were produced, resulting in a 76% yield. How could the student determine the initial amount of sulfur used?
O A. Convert moles of iron (III) sulfide to moles of sulfur using the mole ratio of 1 mole Fe,S:3 mole S.
O B. Convert moles of iron (III) sulfide to moles of sulfur using the mole ratio of 3 mole Fe,S;:1 mole S.
C. Determine the moles of iron (III) sulfide if 100 percent were reacted by placing 76% equal to 0.32 moles/x and then converting moles iron (III) sulfide to moles of sulfur using the mole ratio
of 3:1.
D. Determine the moles of iron (III) sulfide if 100 percent were reacted by placing 24% equal to 0.32 moles/x and then convert moles of iron (III) sulfide to moles of sulfur using the mole ratio
of 3:1.
