 The  % error is  =  11.0 %

calculation

  percentage error  =    (Exact  value  -Approximate value) / exact amount  x100

Approximate value = 8.9 g
Exact  value = 10.0 g
 Percentage  error is therefore =  {(10.0 - 8.9)  /10.0} x100

 (1.1 g/ 10.0) x100 = 0.11 x100  = 11.0%

Take the absolute value of 10.0 - 8.90/10.0 to get 0.11 then multiply that by 100 percent to get 11 percent
