The acidity constant (Ka) of acetic acid is 1.8×10-5. Calculate the % error of your measured Ka value. (What is the percent error?)?

Update:

The Ka value= (might be) 0.000010 or 0.000018 ?? (asked this in another q and got ignored sooo....)

    In order to calculate a % error, you must have an experimental value. The general formula for % error is:

    % error = (|actual - experimental| / actual) X 100

    What is  YOUR measure Ka value??  I assume you have one a lab to find the Ka -- that is YOUR measure Ka value.  

      I didn't measure the Ka
