Answer: There are 6.9 mol of
are required to react completely with 2.30 mol of S.
Explanation:
The given reaction equation is as follows.

Here, 1 mole of S is reaction with 3 moles of
which means 1 mole of S requires 3 moles of
.
Therefore, moles of
required to react completely with 2.30 moles S are calculated as follows.

Thus, we can conclude that there are 6.9 mol of
are required to react completely with 2.30 mol of S.
