 on compleation of a recent Titration I found the percentage error of my results. I used two methods to find my results, the first was a calibration curve and the second was a series of calculations.  the percentage error for the calabration curve was 3.077% and for the calculations it was 6.154%. Why is my percentage error so much higher from the calculation method?

what was the right answer based on, where you compared your 2 calculated values to?
