The Percent error in the calculation of densities of the metal during experiment is 0.03 %
<h3>What is Percentage error?</h3>
Percent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage.
Percent error = [Experimental value - Theoretical value] / Theoretical value x 100%
Percent error = 7.83 -7.86 / 7.86 x 100
= 0.03 %
