Calculate the number of sodium ions and chlorine ions and total number of ions in 14.5g of NaCl ?
Here is what I get:
Now, this equates to
We get this if we multiply 0.248 mol with Avogadro's number,
Each molecule of Sodium chroride holds two atomic ions bonded in an ionic bond-
Number of Sodium ions=Number of Chloride ions=
So the total amount of ions is twice this number,
