Experimental uncertainty arises because of: Limits in the how exact the measuring apparatus is. Maximum Percentage Error When I finish my titration the volume reads 35.6cm3.” “The volume I used in the titration is 12.4cm3 (48cm3 – 35.6cm3)” “I took two reading from the burette therefore my uncertainty Percentage errors!??? or can the Mods just move it Last edited by Couldxbe; 13-03-2007 at 19:39.

Divide actual yield by theoretical yield to get the percentage error (sometimes aka percentage yield) hi O__o · 10 years ago 0 Thumbs up 0 Thumbs down Comment Add a comment c.) the percentage error in the measured length of the field Answer: a.) The absolute error in the length of the field is 8 feet. Each side has an error value which can be compared. Only these two figures convey significant information.
Use your answer to calc the percentage error in the titre volume of 11.30cm³ My answer: ± 0.05cm³ (0.05*2)/11.30 * 100 = 0.88% which was correct If I try it with Thanks. eloise · 2 months ago 0 Thumbs up 0 Thumbs down Comment Add a comment Submit · just now Report Abuse . . . . . . . . . . if you're talking about percentage errors in experimentation compared with theory, u put the difference in the theoretical and practical value over the theoretical value, times a hundred.
