Copper's accepted density is 8.96 g/cm3. Percent Error Worksheet The result of the difference is positive and therefore the percent error is positive. This will convert the answer into percent form.

It is used in chemistry and other sciences to report the difference between a measured or experimental value and a true or exact value.

Example: I estimated 260 people, but 325 came. 260 − 325 = −65, ignore the "−" sign, so my error is 65 "Percentage Error": show the error as a percent of Flag as... Share it. Percent Error Definition Chemistry Flag as...
