13-22. The arsenic in a 1.203-g sample of a pesticla was converted to H2ASO4 by suitable treatment. The acid was then neutralized, and 40.00 mL of 0.05871 M AgNO, was added to precipitate the ar- senic quantitatively as Ag3AsO4. The excess Ag* in the filtrate and in the washings from the precipitate was titrated with 9.63 mL of 0.1000 M KSCN, and the reaction was *13 Ag* + SCN AgSCN(s) Find the percentage of As,O, in the sample.

How did you calculate frquency
Express Surgery Center's (ESC) preferred stock, which has a par value equal to $160 per share, pays an annual dividend equal to 10 percent of the par value. If investors require a 14 percent return to purchase ESC's preferred stock, what is the stock's market value? Do not round intermediate calculations. Round your answer to the nearest cent.
2. When making the calibration curve in Part 1 of the experiment, it was assumed that the reaction mixture went to completion. That is, you assumed that [SCN] = [FeNCS2+]eq when the [Fe3+]o was in large excess. Using your average Keq (Part 2), calculate the equilibrium concentrations of each species in the last mixture (2mL Fe3+ and 225μL SCN-) of Part 1. a. [Fe3+]eq (M) b. [SCN]eq (M) c. [FeNCS²+]eq (M)
