Barium sulfate, BaSO4, is used in medical imaging of the GI tract because it is opaque to X rays. A barium sulfate solution, sometimes called a cocktail, is ingested by the patient, whose stomach and intestines can then be visualized via X ray imaging. If a patient ingests 360 mL of a saturated barium sulfate solution, how much toxic Ba2+ ion has the patient consumed?
The solubility of Ksp of BaSO4 is 1.1x10^-10.
Mass of Ba2+ = _______g
