Answer:
4.81%
Explanation:
Experimental error (also known as percent error) is the positive difference between the calculated value and the actual value divided by the actual value.
[tex]\%\ error = \frac{|actual-experimental|}{actual}[/tex]
The actual density of aluminum is 2.70 g/cm³. So the experimental error is:
%error = |2.70 − 2.83| / 2.70
%errror = 0.13 / 2.70
%error = 0.0481
%error = 4.81%
