Question

Consider the densities of the
metal in the table to the right.
The metal was thought to be
iron (density = 7.86 g/cm³).
What is the % error?
Trial #
Density

7.92
2
7.73
3
7.84
Average 7.83

Answer 1

The Percent error in the calculation of densities of the metal during experiment is 0.03 %

What is Percentage error?

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 %
