How many moles of Cl ions are there in 8.5 moles of CaCl2 ?
To determine the number of moles of Cl ions in 8.5 moles of CaCl2, we need to consider the solubility of the compound.
The compound CaCl2 dissociates into one Ca2+ ion and two Cl- ions. This means that for every mole of CaCl2, there are 2 moles of Cl- ions.
Therefore, in 8.5 moles of CaCl2, there would be:
8.5 moles of CaCl2 * 2 moles of Cl- ions/mol of CaCl2 = 17 moles of Cl- ions.
So, there are 17 moles of Cl ions in 8.5 moles of CaCl2.
