After I finished my chemistry lab, my results for the density of Iron was 7.9 g/ml, the expected result was 7.86 g/ml Now I need to find the percent error, I've tried doing the equation many times, but I'm not sure if I'm right...

So... (7.86-7.9) / (7.86) = .00508 x 100 (for percent) = .508 %, depending on how much you want to round.

Well, first you would subtract 7.9 from 7.86 which would be -.04. Then you would divide that with 7.86 expected result which would be -.005, then multiply by 100, which equals -.5, so the absolute value is -.5, percent erro

I am in a physics class and on our HW, we have to calculate percent difference and percent error. He gave us the equation for percent difference as |observed value - actual value|/ actual...but I thought that as the same as the equation for percent error.

Trending Now Isla Fisher One Direction Tony Romo Michelle Obama Business Cards Cheap Airline Tickets Atlanta Falcons Online MBA Kevin Hart The Eagles Answers Relevance Rating Newest Oldest Best Answer: Percent Difference: Applied when comparing two experimental quantities, Exp1 and Exp2, neither of which can be considered the “correct” value. The percent difference is the absolute value of the difference over the mean times 100. mean = (E1 + E2)/2 % Difference = |E1 − E2| / mean Where as the Percent Error: Percent Error: Applied when comparing an experimental quantity, Exp, with a theoretical quantity, T, which is considered the “correct” value. The percent error is the absolute value of the difference divided by the “correct” value times 100. % Error = |T − Exp|*100 / T Source(s): Que · 9 years ago 4 Thumbs up 1 Thumbs down Comment Add a comment Submit · just now Report Abuse Percent Difference Source(s): https://shrink.im/a7WlV perinovic · 3 weeks ago 0 Thumbs up 0 Thumbs down Comment Add a comment Submit · just now Report Abuse This Site Might Help You.
