Exposure to arsenic can result to subacute to severe toxicity and can sometimes be lethal and cause death. One source of arsenic is from agricultural runoffs. The concentration of arsenic in an agricultural wastewater is determined gravimetrically. A 25.0000 g sample of wastewater was precipitated as MGNH,AsO, and isolated as Mg,As,O7. Determine the %w/w_ of As,O, in the sample if it yields 1.5610 of Mg,As,O7.
