How many moles of P4O10 can be produced with 9.544 x 10^-1 moles of the limiting reagent?

I showed you how to do this. You do this on your own and post your work. I'll check it. However, first you need the equation; otherwise, you won't know what the limiting reagent is.

The limiting reagent is P

Write the balanced equation and follow that last post.

To determine the number of moles of P4O10 that can be produced, we need to use the concept of the limiting reagent. The limiting reagent is the reactant that gets completely consumed in a chemical reaction, thereby limiting the amount of product that can be formed.

To find the limiting reagent, we need the balanced chemical equation for the reaction. Unfortunately, you haven't provided the chemical reaction. Please provide the balanced equation, and I'll be able to help you further.

Once we have the balanced equation, we can use the stoichiometry of the reaction to determine the number of moles of P4O10 that can be produced from a given amount of the limiting reagent.
