Therefore the limit of accuracy is One thing to note when using burettes: you will be taking two measurements(one at the start and one at the end), therfore the total uncertainty d is incorrect because ±1% of 100 is ±1 where as ±1% of 0 is 0 this makes c the correct answer just remember that percentage uncertainties are constant and actual Thank you :) Best Answer Yes, and yes, IF U add the +/- :>) Calculating uncertainty physics? A quick way of working out the uncertainty is that if the scale goes up by 0.1, we just halve it so the limit of accuracy would be 0.05. http://www.thestudentroom.co.uk/showthread.php?t=750197
