- Analysis of 3-ethyl-3-buten-2-ol gave C, 72.13%; H, 11.92%. Calculate the percent deviation of these results from the theoretical values for C and H.
- When 6-chloro-2-methyl-3-cyclohexenol was submitted for elemental analysis, the results were C, 51.07%; H, 7.96%; Cl, 21.53%. Are these values within the required ±0.4% of theoretical? If not calculate the apparent empirical/molecular formula and suggest the identity of the contaminant.

Data Analysis C. Transfer the hydronium concentration, [H3O+] from Table 2 to Table 3 for each sample. Based the measured hydronium concentration in Table 2, infer the concentration of C2H302. For each solution above, considering the amount of HC2H2O2 that must have ionized to give the measured concentration of [H3O+] and the stated concentration of HC2H2O2, calculate the remaining concentration of HC H:02. Record those values in Table 3 for each solution. Show the details of the calculations in your...
