A reaction's is simply the number of grams of a product that you actually get for every $"100 g"$ of said product that you could theoretically get.

The number of grams of a product that can theoretically be obtained by a reaction is called the theoretical yield. This value is calculated using stoichimetry and assuming that the raction has a $100%$ yield.

The number of grams of a product that are actually produced by a reaction is called the actual yield. This value is detemined experimentally, i.e. by actually doing the reaction.

In your case, the reaction has a theoretical yield of $"65.3 g"$ and an actual yield of $"56.3 g"$.

Since your goal is to determine the number of grams produced for every $"100 g"$ that could theoretically be produced, you can use this ratio as a conversion factor

$100 color(red)(cancel(color(black)("g theoretically"))) * "56.3 g actually"/(65.3color(red)(cancel(color(black)("g theoretically")))) = "86.2 g actually"$

Thsi means that the reaction has a percent yield of

$color(darkgreen)(ul(color(black)("% yield = 86.2%")))$

For every $"100 g"$ of product that could be produced, the reaction produces $"86.2 g"$ of product.

The answer is rounded to the .

Given the following, what is the limiting reactant? What is the theoretical yield of $Cl_2$? If the yield of the reaction is 75.5%, what is the actual yield of chlorine?

This is a limiting reactant problem. We know that we will need a balanced equation with masses, molar masses, and moles of the involved. 1. Gather all the information...

How do the actual yield and the theoretical yield from a reaction compare?

This is so since there might be some impurities in the reactants (ie they are not 100% pure form) and so not 100% yield can be obtained in this case.

What is the theoretical yield and percent yield of $"AgCl"$ if $"102.6996 g CsCl"$ reacts with excess $"AgNO"_3"$? The actual yield of $"AgCl"$ is $"77.938858 g"$.

This is a double replacement (double displacement reaction). Balanced Equation $"CsCl(aq)"+"AgNO"_3("aq")$$rarr$$"CsNO"_3("aq")+"AgCl(s)"$ Molar Masses We need the molar masses of $"CsCl"$ and $"AgCl"$. $"CsCl:"$$"168.358452 g/mol"$ $"AgCl:"$$"143.3212 g/mol"$ Theoretical...

Stoichiometry predicts that the yield of beryllium chloride is 10.7 grams. If my actual yield was 7.6 grams, what was my percent yield?

Of course you need a stoichiometric equation to represent the $BeCl_2$ synthesis.

If a reaction has an actual yield of 5 grams and a theoretical yield of 10 grams, what is the percent yield?

Let's define those three terms before we get started: The percent yield of a reaction is the ratio of actual yield to the theoretical yield times one-hundred percent....

In the neutralization of sulfuric acid with sodium hydroxide, the theoretical yield from 6.9g of sulfuric acid is 10g. In a synthesis, the actual yield is 7.2g. What is the percentage yield for this synthesis?

And thus for this example $%"Yield"$ $=$ $(7.2*g)/(10*g)xx100%$ And we don't even need a calculator......... Most of the time, we write a stoichiometric equation, that shows the molar equivalence between...

For the reaction $"PCl"_3(g) + "Cl"_2(g) -> "PCl"_5(g)$, the percent yield was $88.2%$ for a certain experiment. If $"77.4 g"$ of $"PCl"_3$ was consumed in the presence of xs $"Cl"_2(g)$, what would be the actual yield of $"PCl"_5(g)$ for this experiment?

$"103.52 g PCl"_5$ You are given the reaction: $"PCl"_3(g) + "Cl"_2(g) -> "PCl"_5(g)$ Since you are given the of $88.2%$, it means that the...

Define the terms theoretical yield, actual yield, and percent yield. Why is the actual yield in a reaction almost always less than the theoretical yield? Can a reaction ever have 110% actual yield?

Actual yield in a reaction is almost always less than the theoretical yield, primarily because losses of the substances involved may occur anywhere in an experiment. Otherwise, there can be...

If the theoretical yield for a chemical reaction is 100. g and the percentage yield is 70.0%, what is the actual yield?

The actual yield is a term used to describe the amount of product that is actually produced by a given chemical reaction. By comparison, the theoretical yield is a...

Carbon disulfide, CS2 can be made from coke, C and sulfur dioxide, SO2: 3C + 2 SO2→ CS2 + CO2. If the actual yield of CS2 is 86% of the theoretical yield, what mass of coke is needed to produce 950g of CS2?

Since $950$ $"g"$ is the desired mass of $"CS"_2$, and the is $86%$, the theoretical yield of $"CS"_2$ is $950$ $"g CS"_2"$ $xx 100/86 = ul(1107color(white)(l)"g CS"_2$ Now, let's...
