filling out and uploading a lab report.

Experiment 1 Instructions Note: You will be filling out and uploading a lab report. Please see this experiments Report template. 1. Download and print out the Report_template for Experiment 3 Density of solid matter. 2. Access link to the youtube video for the experiment: https://www.youtube.com/watch?v=CzcdByf9ZC0 (Links to an external site.) 3. Use Data Table in the template to record volume and mass for each object. 4. Calculate Density for the object in Data Table. 5. Show all calculations below the table for each part. 6. Quality of results: 1) Lookup/Google some of the density values for some of those objects as best as you can 2) How do those standard values compare to yours from the simulator? What did you learn from the experiment? Any changes?

Synthesis of Aspirin

Synthesis of Aspirin Instructions 1) The experiment is just the 1 link Synthesis of Aspirin. In the link, the UK Professor has a bit of an accent, so I suggest turning on closed captioning. 2) You will follow along with his lecture about the experiment. Since the experiment isn’t all written out, I provided for additional background information, a pdf of the face-to-face version we have performed at BRCC. The reaction is the same, it is just the numbers are different of course. 3) As you follow the UK professor through the experiment make notes of what he is doing and weighing in the procedure section of the report template. And record his numbers as he records them in his report document. 4) then you will follow along with his calculations and reproduce them in the data analysis section of your template. 5) For your conclusion, discuss problems with the experiment and why, percent yield.
