The Crucible Formula Lab Report

The first step in the experiment was to measure the mass of the crucible for trial 1. The second step was to add the Sodium bicarbonate using the scoopula into the crucible. The mass of the crucible and the Sodium bicarbonate was weighed. Next, the mass of just the Sodium bicarbonate was determined by subtracting the mass of the crucible and the substance by the mass of the crucible by itself. For all three trials, the mass of just the Sodium bicarbonate was exactly 2 grams. This was done on purpose to make sure that the final mass of the heated substance was accurate. Then, the crucible was heated over the bunsen burner for approximately 4 minutes using the clay triangles as support. Once the 4 minutes were over and the crucible cooled off,
the mass was measured again. The initial mass of the crucible and Sodium bicarbonate was subtracted from the mass after being heated to find the mass of how much Sodium bicarbonate was leftover. The same process was repeated two more times, except the crucible was heated for 6 minutes instead of 4 minutes.
