WebBy this definition, the number of equivalents of a given ion in a solution is equal to the number of moles of that ion multiplied by its valence. For example, consider a solution of 1 mole of NaCl and 1 mole of CaCl2. The solution has 1 mole or 1 equiv Na+, 1 mole or 2 equiv Ca2+, and 3 mole or 3 equiv Cl− . WebTo convert the moles of Cl – to number of Cl – ions, we use the equivalence, 1 mole Cl – = 6.02 x 10 23 Cl – ions. The conversion factors are: In 6.75 grams of MgCl 2, there are 8.54 x 10 22 chloride ions. When asked how many ions, atoms, molecules, etc., use Avogadro’s number.
