Now we have to calculate the Percent Error by doing: |Accepted Value - expirimental Value| \ accepted value x 100% I don't know what i should put in for the accepted Solve for percent error Solve for the actual value. http://ebprovider.com/percent-error/chemistry-formula-for-percent-error.php
Calculate the percent error of your measurement.Subtract one value from the other:2.68 - 2.70 = -0.02 Depending on what you need, you may discard any negative sign (take the absolute value): 0.02This then for the accepted value, you have to put in the value that is most accurate and precise, for this you should really ask you teacher. You can only upload a photo or a video. 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 http://sciencenotes.org/calculate-percent-error/

Copper's accepted density is 8.96 g/cm3. Percent Error Formula Chemistry Absolute Value if the accepted value was 2.70 then you will do: (2.88-2.70) / 2.70 x 100% u will get: 0.18 / 2.70 x 100% 0.06666666666666 and so one x 100% you will You measure the dimensions of the block and its displacement in a container of a known volume of water. The error comes from the measurement inaccuracy or the approximation used instead of the real data, for example use 3.14 instead of π.
