43. Solving a chemistry problem

494. A weighing of 0.5663 grams of arsenic (III) oxide was transferred into a solution and 250.0 ml of an acidified solution was obtained. 11.15 ml of potassium bromate solution was used to titrate a 10.00 ml aliquot in the presence of methyl orange. 0.10 ml of titrant was used for titration of the indicator in the "blank experiment". Calculate the molar concentration of the titrant equivalent and its titrimetric conversion factor for antimony (III).
