Transcript The interactive transcript could not be loaded. In my individual calculation the density for Aluminum was 2.88 and Iron was 8. Calculate Percent Yield Chemistry If you need to know positive or negative error, this is done by dropping the absolute value brackets in the formula. In most cases, absolute error is fine.
The error comes from the measurement inaccuracy or the approximation used instead of the real data, for example use 3.14 instead of π. More questions In chemistry is the percent error calculated in significant digits? You measure the dimensions of the block and its displacement in a container of a known volume of water. http://ebprovider.com/percent-error/chemistry-equation-for-percent-error.php Since the experimental value is smaller than the accepted value it should be a negative error.
