Hello Tj

 

%-Error = ((accepted value - experimental value) / accepted value) x 100%

 

Note!  In the above equation, the absolute value of the numerator must be used in the event you get a negative # as is the case in this problem.

 

%-Error = (Ι (7.13 - 9.95) l / 7.13) x 100%

 

              = | -2.82 | / 7.13 x 100% = 39.6%
