## How To Calculate Percent Error In Chemistry

The post has been corrected. To measure precision, just measure something a whole bunch of times with some measuring tool. For example, if my cat weighs 6500 grams and a scale said it weighed 6400 grams, this measurement would have moderately good accuracy. ie.

For example, you would not expect to have positive percent error comparing actual to theoretical yield in a chemical reaction.[experimental value - theoretical value] / theoretical value x 100%Percent Error Calculation We'll assume you're ok with this, but you can opt-out if you wish.Accept Read MorePrivacy & Cookies Policy Send to Email Address Your Name Your Email Address Cancel Post was not The error comes from the measurement inaccuracy or the approximation used instead of the real data, for example use 3.14 instead of π. What Is A Good Percent Error For example,, in experiments involving yields in chemical reactions, it is unlikely you will obtain more product than theoretically possible.Steps to calculate the percent error:Subtract the accepted value from the experimental value.Take

Change Equation to Percent Difference Solve for percent difference. The mass of the element is 10.23 g The volume of the water it was placed in was 20.0 mL The volume of the water after the element was placed in so 10.23g/1.5mL=6.8 g/mL (you round to 6.8 because you must have only 2 significant digits). A very dense object has tightly packed, or compact, matter....
