The arsenic in a 1.233-g sample of a pesticide was converted to H3AsO4 by suitable treatment. The acid was then neutralized, and 41.00 mL of 0.05819 M AgNO3 was added to precipitate the arsenic quantitatively as Ag3AsO4. The excess Ag+ in the filtrate and in the washings from the precipitate was titrated with 9.89 mL of 0.1000 M KSCN, and the reaction was Ag+ + SCN- ---> AgSCN (s)
Find the percentage of As2O3 in the sample.
Percentage of As2O3 = ____%
