How many moles of ions are released when 0.27 mol of cobalt(II) chloride, CoCl₂, is dissolved in water? A)0.81 mol B)0.54 mol C)0.27 mol D)0.18 mol E)0.090 mol

Question

Quizplus · Accepted Answer

Cobalt(II) chloride (CoCl2) dissociates into one Co2+ ion and two Cl- ions in solution. Therefore, for every mole of CoCl2 dissolved, 3 moles of ions are produced (1 mole of Co2+ and 2 moles of Cl-). Thus, 0.27 mol of CoCl2 will produce 0.27 mol * 3 = 0.81 mol of ions.
