Buffers Additional questions 1: Determine the pH of 50.00 mL of a 0.0500 M HCl solution. Compare this value to your experimental value. 2: Determine the pH of 50.00 mL of a 0.0500 M CH3COOH solution. Compare this value to your experimental value. Comment. Hi, I'm stuck on these questions not sure if I answered them right as my instructor mentioned that there are some errors in the additional questions. In the first one, the comparison is incorrect. In the second one, the calculation and the comparison are incorrect.

The number of defects that are found on inspected assemblies follows a Poisson distribution with parameter $\lambda = 0.02$. a. What is the probability that an assembly will have exactly one defect? b. What is the probability that an assembly will have exactly one or more defects? c. What is the mean (expected value) and variance of the number of defects found on the assemblies inspected? d. Suppose that you found five consecutive assemblies each with two or more defects. If $\lambda = 0.02$, what are the chances of observing this again? What is your conclusion about $\lambda$?
