Answer:
5% is the percent error
Explanation:
Percent error is defined as the 100 times the ratio of absolute value of the difference between the measurement and the theoretical value and the theoretical value, that is:
[tex]\frac{|Theoretical-Measurement|}{Theoretical} * 100[/tex]
In the problem, theoretical value is 5.80g and the measurement is 5.51g:
[tex]\frac{|5.80g-5.51g|}{5.80g} * 100[/tex]
% =
