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 ]

A 0.5 tm-thick InGaAs sample is measured using the Hall effect. A current of 0.2 mA is passed through the sample in a magnetic field of 0.3 T. and a Hall voltage 0.4 mV is detected. 1)What is the electron concentration in the sample, given the charge of an electron is 1.6 x - 10'9 C? 2)Explain why it would be difficult to measure a sample of copper of the same thickness (with an electron concentration of 8.5 x 028 m-3) using the same apparatus. How might the experiment be modified? 3)The InGaAs sample is then excited with light, such that along its length of 2 mm there is a change in electron concentration of 3 x 1018 cin-3. Assuming that there is a linear variation in electron concentration with distance, and the diffusion constant of electrons in InGaAs is' 250 CM2S-1, calculate the current density.
