The formula is given by: The experimental value is your calculated value, and the theoretical value is your known value. A percentage very close to zero means you are very close to your targeted value, which is good. It is always necessary to understand the cause of the error, such as whether it is due to the imprecision of your equipment, your own estimations, or a mistake in your experiment.Example: The 17th century Danish astronomer, Ole Rømer, observed that the periods of the satellites of Jupiter would appear to fluctuate depending on the distance of Jupiter from Earth. The further away Jupiter was, the longer the satellites would take to appear from behind the planet. In 1676, he determined that this phenomenon was due to the fact that the speed of light was finite

It is often used in science to report the difference between experimental values and expected values.The formula for calculating percent error is:Note: occasionally, it is useful http://astro.physics.uiowa.edu/ITU/glossary/percent-error-formula/ to know if the error is positive or negative. If you need to know positive or negative error, this is done by dropping the absolute value brackets in the formula. In most cases, absolute error is fine. For example,, in experiments involving yields in chemical reactions, it is unlikely you will obtain more product than theoretically possible.Steps to calculate the http://sciencenotes.org/calculate-percent-error/ percent error:Subtract the accepted value from the experimental value.Take the absolute value of step 1Divide that answer by the accepted value.Multiply that answer by 100 and add the % symbol to express the answer as a percentage.Now let's try an example problem.You are given a cube of pure copper. You measure the sides of the cube to find the volume and weigh it to find its mass. When you calculate the density using your measurements, you get 8.78 grams/cm3. Copper's accepted density is 8.96 g/cm3. What is your percent error?Solution: experimental value = 8.78 g/cm3 accepted value = 8.96 g/cm3Step 1: Subtract the accepted value from the experimental value.8.96 g/cm3 - 8.78 g/cm3 = -0.18 g/cm3Step 2: Take the absolute value of step 1|-0.18 g/cm3| = 0.18 g/cm3Step 3: Divide that answer by the accepted value.Step 4: Multiply that answer by 100 and add the % symbol to express the answer as a percentage.0.02 x 100 = 2 2%The percent error of your density calcu

Will rate LifeSaver: These percentage error are my trial numbers: Initial mass of copper anode: 36.04 g Initial mass of copper cathode: 34.89 g Time of electrolysis: 15 Min. Current: .5 amp Final mass of copper anode: 36.02g Final mass of copper cathode: 35.41g 1. Mass of copper oxidized at anode (g) = 36.04g – 35.89g = .15g 2. Moles of copper oxidized (mol) = .15/63.55 = .0024 mol 3. Moles of electrons transferred (mol percentage error in e-) Cu(s) => Cu2+(aq) + 2 e- = 2 x .0024 = .0048 mol 4. Coulombs passed through cell (C) = Current (in Amperes) x time (in seconds) = Current (in Amperes) x 15 x 60 .5 x 15 x 60 = 450 5. Electrons passed through cell (e-) 450 / 1.6 x 10-19 = 2.8 x 1021 6. Avogadro's number (e-/mol e-) 2.8 x 1021 / .0048 mol = 5.8 x 10²³ 7. Average value of Avogodro's number = Average of all your calculated values for Avogadro's number: My total from another trial for this question was 1.7 x 10²³ so my average is: 5.8 x 1021 + 1.7 x 10²³ = 7.57 x 1023 / 2 = 3.8 x 10²³ 8. Literature value of Avogodro's number = 6.02 x 1023/mol 9. Percent Error = 100% x (Average value of Avogadro's number - Literature value of Avogadro's number)/Literature value of Avogadro's number: 100(3.8 x 1023 – 6.02 x 1023) / 6.02 x 1023 = -37% 10. Faraday constant (C/mol e-) = Coulombs passed through cell/Moles of electrons transferred. 450 / .0048mol = 93750 coulombs 11.
