Analysis

Measure the mass and melting point of your final product.

mass of empty flask

The photo shows a small glass filter flask resting on top of a laboratory scale. The screen on the scale reads “39.0510 g.”

mass of flask + product

The photo shows a small glass filter flask resting on top of a laboratory scale. The bottom of the flask is fogged somewhat, indicating that a small amount of fine powder or oil may be present in the bottom. The screen on the scale reads “39.0654 g.”

The video has two frames. On the left, a thin glass capillary tube has been inserted into a metal slot. The bottom of the tube contains a small portion of off-white solids. On the right, we see the screen of a LabQuest2 device that provides readings corresponding to the temperature of the metal holder on the left. As the video progresses, the temperature readings on the screen rise steadily and the off-white solids in the tube melting into a clear liquid. Please seek assistance in determining the precise temperatures at which these changes occur.

You're almost done! Time to clean up...
