Question

A chemist estimated the volume of a solution in a test tube to be 30ml. The actual volume of the solution was 32.5ml. Find the absolute error and the percent error of the chemist's estimate. If necessary, round your answers to the nearest tenth.

absolute error= ? ml
percent error = ?%

Answer 1

2.5 ml .

7.7 % to the nearest tenth.

Explanation:

The absolute error is 32.5 - 30 = 2.5 ml.

The percent error is (2.5 / 32.5) * 100 = 7.69%
