There are no other reactants or products.

How many moles are prepared from????
0.2





.25 moles * 8/10


you need 10 atoms of S in the product. The reactant has only 8, so for every .25 moles of S8, you will get .25 * 8/10 of reactant.
Reply:4P4 + 5S8 --%26gt; 4P4S10





You need 5 moles of S8 to react with 4 moles of S4


S8 is the limiting reagent.





0.25 moles S8 x (4/5) = 0.20 moles of P4S10
