When 5.0 g CaCl₂ is dissolved in water, how many moles of ions are in solution?

Question

Quizplus · Accepted Answer

The formula CaCl2 dissociates into 3 ions in solution: one Ca2+ ion and two Cl- ions. To find the number of moles of CaCl2, we use the molar mass of CaCl2 (approximately 111 g/mol). Thus, 5.0 g CaCl2 / 111 g/mol = 0.045 moles of CaCl2. Since each mole of CaCl2 produces 3 moles of ions, the total moles of ions are 0.045 moles * 3 = 0.135 moles.
