Experiment 1 post lab questions

Post Lab Questions for Part C: 1. From your data for part C above, which glassware is most accurate? Least accurate­­­­? 2. Look at volume error. What effect does glassware diameter at calibrations have on volume error? 3. What glassware is slowest to clean and use? What aspect of design makes it precise and/or accurate? 4. The G W0 calculations confirm the trend of a smaller band gap (0.75 to 1.05 eV) in A NiSn compared to the A CoSb compounds (1.13 to 1.44 eV) already expected from the GGA calculations. While in A NiSn materials the G W0 band gap is 20% to 50% larger than in HSE06, the fundamental gap of A CoSb materials is smaller in G W0 compared to HSE06. S.
