Purpose: The purpose of this lab is to learn how to properly use the top-loading balance, analytical balance, buret, and pipet to correctly evaluate mass, volume, and density. Procedure: Please see pgs. 4 and 5 of General Chemistry Laboratory Experiments, Volume 1 by Report Form: See attached report form and sample calculations sheet. Report Questions: 1. The mass of the crucible cover was obtained through the use of two different methods in the experiment. One value was found through simple difference between combined mass and crucible mass. The other value was found through measuring the cover directly with the balance. In the data collected, from part A of the experiment, the average values were the same for both methods. In turn, the average deviations were the same for both methods. This is because the top-loading balance was only accurate to the hundredth place, which doesn't leave much room for inaccuracy. Thus, the masses were all the same within ±0.01, allowing for an average deviation to be 0.00 for all values. In part B, where the analytical balances were used,
