Monica performed Part B of Experiment VOL and monitored the current every two minutes as instructed in Step 20. She noticed throughout the experiment the current displayed on the voltmeter repeatedly drift above the current she initially set, so every two minutes she adjusted the power supply to account for this "current drift." She uses the target current to calculate the moles of metals reduced or oxidized at the electrodes. Then determines the atomic masses of her assigned electrodes using the mass gained/lost at the electrodes and calculated moles of metal. The current drift will [Select ] the flow of electrons. This will [ Select ] * the actual moles of electrons transferred from the [Select] leading to [Select ] moles of metal reduced or oxidized at the electrodes. Hence, the atomic weight will be [ Select ]
