3. Calculation
an example of the calculation for Boyle's Law – PV calculation [5]
Boyle's Law graph [5 pts]
how was the experimental value of absolute zero determined [5]
calculate the percent difference from absolute zero value [5]
Charles's Law graph [5 pts]
calculations for the N2 gas – see page 27 of the lab manual [5]
calculate the average percent yield and standard deviation for the N2 production for pure NaNO2
and the unknown sample [5]
calculate the percent difference for N2 for both the pure and unknown samples [5]
4. Results and Discussion
discuss whether the graphs look like expected or not. [10]
compare the literature and experimental values of absolute zero (explain what possible errors might
contribute to the deviation) [10]
compare the theoretical and experimental values for N2 [10]
discuss the experimental results for the unknown samples [10]
5. Conclusion
give an overall summary of the experiment [5]
