Achemist measured 184 ml using a graduated cylinder. based on her experience, the volume did not seem to be correct. this volume was again measured using a calibrated standard device, from which it was determined that the volume of the liquid was actually 230.0 ml. what is the % error in this measurement?

Percent error = 20%

Explanation:

The percent error is calculated using the following equation:

Percent error = |(approximate value - exact value)| / (exact value) x 100%

In this problem, the approximate value was 184 mL and the exact value was 230.0 mL

Percent error = |(184 mL - 230.0 mL)| / (230.0 mL) x 100% = 20%
