Answer to Question #57244 in General Chemistry for Rachel

Question #57244
For a work sheet i got this question: A 5.00 g sample of a crude sulfide ore in which all the sulfur was present as As2S5 was analyzed as follows: The sample was digested with concentrated HNO3 until all the sulfur was converted to sulfuric acid. The sulfate was then completely precipitated as BaSO4. The recovered BaSO4 had a mass of 0.752 g. Calculate the percent of As2S5 in the crude ore. For me the question is worded strangely, so i do not know how to arrange the components in the products and reactions to write the formula.
