.2M x V FeCl3=moles FeCl3 x 1mole Fe2S3/2mole FeCl3=moles of Fe2S3 x mm of Fe2S3/1 mole Fe2S3= g Fe2S3 x .65% yield.
2.75g Fe2S3/ .65= 4.23g Fe2S3/ 207.91= .02035 x 2mole FeCl3=.0407 moles FeCl3/ .2M FeCl3= .2035 L x 1000= 203.5 ml

How many milliliters of 0.200 M FeCl3 are needed to react with an excess of Na2S to produce 0.690 g of Fe2S3 if the percent yield for the reaction is 65.0 3 Na2S(aq) plus 2 FeCl3(aq) Fe2S3(s) plus?
To find the moles of Fe2S3 produced, convert 0.690 g to moles using the molar mass of Fe2S3. Then, use the stoichiometry of the reaction to determine the moles of FeCl3 required. Finally, use the molarity of FeCl3 to calculate the volume in milliliters needed, keeping in mind the percent yield.

How many moles of Co2 will be produced from the reaction of three moles of acetylene with excess oxygen?
Since acetylene (C2H2) has a stoichiometry of 2 moles of acetylene to produce 2 moles of CO2, three moles of acetylene would produce 3 moles of CO2. The reaction with excess oxygen ensures that all the acetylene is fully converted to CO2.
How do you determine the limiting agent and excess?
The limiting agent in a chemical reaction is the reactant that is completely consumed first, stopping the reaction. To determine the limiting agent, calculate the amount of product each reactant can produce and identify the one that produces the least amount of product. The other reactant is then in excess.
What does the term excess mean in chemistry?
In chemistry, the term "excess" refers to a reagent that is present in a higher quantity than what is required for a reaction. It is typically used to ensure that all the other reactants are fully consumed in the reaction. The excess reagent does not limit the reaction's progression and is usually added to ensure maximum yield.
