This means that even though the smallest division on the front scale of the balance corresponds to 0.01 g, no estimating is done between the divisions. This is the only exception you will encounter in lab to the rules described in experiment 1 about using ruler-like scales. The result is that accurate masses determined using a centigram balance will be recorded only to the nearest 0.01 g Question Asking Tips Ask one academic question at a time - Keep questions specific and include all details - Contact Support for textbook, writing, or account help b.

Errors of different varieties may arise throughout the course of an experiment. Below, match the different types of errors with their corresponding definitions. Group of answer choices Errors that have an equal chance to be positive or negative. These errors will arise because it is impossible to make any measurement completely exact. Errors that will have a consistent directional bias every time the experiment is carried out. These errors tend to always be positive or negative, meaning over or underestimating, respectively, the true value of the measurement due to experimental limitations. An error that is within the direct control and/or caused by a mistake from the chemist. Options Random error Systematic error Human mistake

Why should the selected rule(s) be followed? Weighing wet items will cause the displayed mass to be greater than the actual mass of the object. A residue left on the balance will contaminate the balance pan surface and anything that comes into contact with it afterwards. Objects at any temperature other than room temperature can create air currents which can affect the balance pan, causing the measured mass to be higher or lower than the true mass. There may be discrepancies in accuracy between individual balances.
