You have calculated the density of aluminum as being 2.83 g/cm^3. what is the experimental error?

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.

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%

568.98
