Answer:
B
Explanation:
This question is about stoichiometry. From the balanced equation ⇒
, we see that 3 moles of water is needed to react with 1 mole of
.
This means that, to fully react 3.62 moles of , we would need 3*3.62 or 10.86 moles of water. However, we only have 6.31 moles, so water is the limiting reactant.
Since 3 moles of water react with 1 mole of , 6.31 moles of water can fully react with 6.31÷3 or 2.1033 moles of
.
From the balanced equation, we see that every mole of reacted gets you 2 moles of
. Therefore, 2.1033 moles of
would give you approximately 4.21 moles of
.
