While doing a lab, a student found the density of a piece of pure aluminum to be 2.85 g/cm3. The accepted value for the density of aluminum is 2.70 g/cm3. What was the student's percent error?

Respuesta :

The equation for percent error is

% Error = [tex]100*|Experimental-Theoretical|/Theoretical[/tex]

Our experimental is 2.85g/cm^3 and the accepted is 2.7g/cm^3

Thus our % Error = 5.555%
