The percent error is 1.82%.


Percent error is the absolute value of the difference between the theoretical value and the experimental value divided by the theoretical value multiplied by 100.


The percent error for the question is:

#"% error" =abs((55.0"g"-56.0"g")/(55.0"g"))xx100=1.82%#

rounded to three significant figures
