Answer 1

2 mol ..................

Answer 2

Hey dear,

● Answer -
2 moles of Zn(FeS2)

● Explanation -
You didn't give amount of sulphur available, so we'll take that as abundant.

For each mole of Zn(FeS2), 1 mole of Zn, 1 mole of Fe & 2 moles of S are required.

Here, S is in abundance, so number of moles of Zn(FeS2) formed will depend on limiting element from Zn or Fe.

Here, we have 2 moles of Zn which will react with 2 moles of Fe and 4 moles of S to form 2 moles of Zn(FeS2).

* 1 mole of Fe will remain unused.

Hope this helps you...
