We react 180.0g Fe2P with 140.0g of S according to the following reaction:
4FeP(s) + 18S(s) -----> 8FeS(s) + P4S10(s)
What is the limiting reactant and how much FeS will be produced (in grams)?
How much of the excess reactant will we have left over in grams?
4Fe2P(s) + 18S(s) -----> 8FeS(s) + P4S10(s)
No of mol of Fe2P = 180/142.6638 = 1.26 mol
No of mol of S = 140/32 = 4.375 mol
limiting reactant = s
4 mol Fe2p = 18 mol S = 8 mol Fes
Mass of Fes formed = 4.375*(8/18)*87.9 = 170.91 grams
excess reactant = 180 - (4.375*(4/18)*142.7) = 41.264 grams
We react 180.0g Fe2P with 140.0g of S according to the following reaction: 4FeP(s) + 18S(s)...

In the following chemical reaction, 2 mol of A will react with 1 mol of B to produce 1 mol of A2B without anything left over: 2A+B→A2B But what if you're given 2.8 mol of A and 3.2 mol of B? The amount of product formed is limited by the reactant that runs out first, called the limiting reactant. To identify the limiting reactant, calculate the amount of product formed from each amount of reactant separately: 2.8 mol A×1 mol...
