Answer:
The correct answer is 18.75 moles X.
Explanation:
We first start with the idea that we have 25.00 moles of D. Next, we must look at the relationships in the balanced equation to find that for every 4 moles of D produced, 3 moles of X are reacted (since it is given that there is excess Y and thus X is the limiting reagent). From this, we can do the following calculation:
25.00 moles D * (3 moles X/4 moles D) = 18.75 moles X
Therefore, your answer is 18.75 moles X.
Hope this helps!
