Approx. $6.0*mol$

We (i) calculate the molar quantity of chloride ions.......

$(1.81xx10^24*"magnesium chloride units")/(6.022xx10^23*MgCl_2*"units"*mol^-1)=3.0*mol$

And since there are TWO moles of chloride ions per mole of salt....

(ii) we could also calculate the mass of this quantity.........
