student is given a rock that is known to have a mass of 436.8 grams. She measures the mass of the rock three different times with the following results: 460.9 g, 461.4g, 459.0 g. Calculate the percent error of the student.

Given :

Actual mass , .

Three observations 460.9 g, 461.4 g, 459.0 g .

To Find :

The percent error of the student.

Solution :

Percent error is given by :

Therefore , the percent error of the student is 16.23 % .

Hence , this is the required solution .
