Copper's accepted density is 8.96 g/cm3. check over here For example,, in experiments involving yields in chemical reactions, it is unlikely you will obtain more product than theoretically possible.Steps to calculate the percent error:Subtract the accepted value from the experimental value.Take Approximate Value − Exact Value × 100% Exact Value Example: They forecast 20 mm of rain, but we really got 25 mm. 20 − 25 25 × 100% = −5 25 Solve for the measured or observed value.Note due to the absolute value in the actual equation (above) there are two solutions. What Is A Good Percent Error

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 You measure the sides of the cube to find the volume and weigh it to find its mass.
