It means that your reaction is extremely efficient, that your product is stable and that there are no side products. Your lab skills are also very good.

However, if you're an undergrad, you likely haven't checked the purity of this. It is likely to be contaminated with some of the excess starting material, catalyst, or side products

Q: What does it mean when the percent yield is 100 percent?

You did something wrong in your calculation or you have some impurity. You never get 100% yield.

Percentage yield = (Actual yield / Theoretical yield) x 100% The percentage yield for a reaction is a value between 0 to 100 percent.

If this is the actual yield, real amount produced, then you need the theoretical yield to find the percent yield. % yield = (actual yield / theoretical yield) x 100

Impurities in the substance can cause a greater percent yield. I recommend redoing the lab for better results.

because 100 percent is the total or the whole and we cant exceed that because in other words it is everything

It is an error (in science).

You did something wrong in your calculation or you have some impurity. You never get 100% yield.

Percent yield = (actual yield/expected yield) x 100

calculating the percent yield.

The percentage yield is the Actual Yield divided by the Theoretical Yield, all multiplied by 100. Percentage = [(Actual)/(Theoretical)] x 100

a percent yield will be above 100 if the product used are wet or more likely impure.

why don't reactions give us a 100 percent yield?

Actual

Do you need it? Are you being told to calculate it? percent yield = (actual yield) divided by (theoretical yield) x 100

Percent yield = Actual Yield / Theoretical Yield * 100 hope that helps :)
