When 6.3 moles of [Co(NH₃)₅Cl]Cl₂ is dissolved in water,how many moles of ions are in solution? A)3.3 B)4.3 C)2.1 D)19 E)57

Question

Quizplus · Accepted Answer

One mole of [Co(NH₃)₅Cl]Cl₂ dissociates into two moles of ions since there are two Cl- ions. Therefore, 6.3 moles of [Co(NH₃)₅Cl]Cl₂ will produce 6.3 x 2 = 12.6 moles of ions. The Cl- ions do not need to be multiplied by two again because they are already included in the 12.6 moles of ions. Therefore, the answer is D) 19.
