Barium sulfate,BaSO4 , is used in medicalimaging of the gastrointestinal tract because it is opaque to Xrays. A barium sulfate solution, sometimes called a cocktail, isingested by the patient, whose stomach and intestines can then bevisualized via X-ray imaging. If a patient ingests 220 ml of a saturated barium sulfate solution, how much toxic Ba+2 ion has the patient consumed?
