For the class average the density of Aluminum was 2.9 and Iron was 7.4. Example: You measure the plant to be 80 cm high (to the nearest cm) This means you could be up to 0.5 cm wrong (the plant could be between 79.5 and Here is how to calculate percent error, with an example calculation.Percent Error FormulaFor many applications, percent error is expressed as a positive value. You measure the sides of the cube to find the volume and weigh it to find its mass.

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 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 Thank you,,for signing up!
