To find percent error. Find published reference materials in a number of chemical reference books and chemical supply catalogs. Subtract the accepted density from the measured density. This value is your 'error'.  continue reading below our video 4 Tips for Improving Test Performance Divide the error by the exact or ideal value (i.e., not your experimental or measured http://sciencenotes.org/calculate-percent-error/

Calculating Percent Error Chemistry

Change Equation to Percent Difference Solve for percent difference. so your equation will look like 10.23g/(21.5mL-20.0mL) you calculate the volume that way because the amount of water that the substance displaces is its volume. In many situations, the true values are unknown. The post has been corrected.
