During the experiment, can the crucible and lid be touched with bare hands? No. If the crucible is still hot, a student can burn his or her hand. No. Dirt and oils on hands can add to the mass of the crucible. Yes. Gloves can be slippery, making it more dangerous to wear them in lab. Yes. They are easier to transport to the balance room and bare hands do not introduce error into the experiment.

Suppose your instructor places a can of regular and diet cola in a large container filled with water. What might you expect happen based on the results of this experiment?
The density of sulfuric acid is 1.84 g/mL. What volume of this acid will weigh 15.7 g? A. 16.0 mL B. 1.84 mL C. 28.9 mL D. 8.53 mL
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.
