Answer:
Step-by-step explanation:
% error= Experimental value- accepted value/ accepted value X 100%
from your previous question the accepted value is 3520 g
% error = 3100-3520/3520 X 100 = -11.93%
In case they ask for % yield
% yield = Actual yield / theoretical yeild x 100%
% yield = 3100/3520 X 100=88.06%
