Question

In an experiment to prepare a particular compound, the theoretical yield s 65.3 g and the actual yield is 56.3 g.  What is the percent yield?

#86.2%#

A reaction's percent yield 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 term "actual yield" refers to the amount of product in grams that are actually produced by a reaction. This value is determined experimentally, that is, by carrying out 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"#

This indicates that the percent yield of the reaction is

#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 solution is rounded to the significant figures.
