Barium sulfate, BaSO_4, is used in medical imaging of the gastrointestinal 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 380 mL of a saturated barium sulfate solution, how much toxic Ba^2+ ion has the patient consumed? The solubility product K_sp of BaSO_4 is 1.10 times 10^-10. Express your answer to three significant figures and include the appropriate units. mass of Ba^2+ = _______ There are some data that suggest that Zinc lozenges can significantly shorten the duration of a cold. If the solubility of zinc acetate, Zn(CH_3COO)_2, is43.0 g/L, what is the solubility product K_sp of this compound? Express your answer numerically. K_sp = _______
