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 http://compaland.com/percent-error/what-is-the-equation-for-finding-percent-error.html

Close Yeah, keep it Undo Close This video is unavailable. The result of the difference is positive and therefore the percent error is positive. 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 to know if the error The absolute value of a positive number is the number itself and the absolute value of a negative number is simply the value of the number without the negative sign, so http://astro.physics.uiowa.edu/ITU/glossary/percent-error-formula/
