Determining Avogadro's Number Lab Data Collection Table 1. Table showing initial mass, final mass and qualitative observation of copper electrodes. Electrode 1 Electrode 2 Initial Mass (g) ±0.005 g 5.77 5.80 Final Mass (g) ±0.005 g 6.27 5.27 Observations The copper electrode is shiny after being placed in copper sulfate. It also appears to have become thicker. The copper electrode is dull after being placed in copper sulfate. It also appears to have become thinner and rusty. Table 2. Table showing current of copper electrodes in 600 second intervals. Time (seconds) ±5 seconds Current (amps - A) ±0.05 A 0 1.1 600 0.7 1200 0.9 1800 1.0 Note: As both copper electrodes were placed in a single beaker of copper sulfate, the data obtained for the current is the same for both electrodes. Thus, the "Current" column in Table 2 represents the current of both copper electrodes. Table 3. Table showing voltage used during the experiment. Voltage (volts) ±0.5 V 6 Data Processing Moles: Number of moles Electrode 2, which lost 0.53 grams after being placed in copper sulfate, contains approximately 0.00834 moles of copper. Uncertainty of moles Uncertainty...
