how do you find the percent error betwwen an experimental value and the accepted value? (of density) thanks

• science -

For example water in grams/cm^3
You do an experiment and get 1.125
the accepted value is 1.00
percent error= 100 (1.00-1.125)/1.00
or
100 (difference/accepted)
in this case
12.5 %
