    the best %percent error should be zero, which means u did the correct process exactly, but this is impossible to attained

    ideal percent error must be near to zero

    % error = (estimate - actual) / actual * 100, in absolute value. Well, first you would subtract 7.9 from 7.86 which would be -.04. Then you would divide that with 7.86 expected result which would be -.005, then multiply by 100, which equals -.5, so the absolute value is -.5, percent error is .5%

    think about it...its how much u were off the theoritcal values....in chem its okay to e ven exceed 200% of experimental error as long as u have enough data to support ur results
