To calculate the number of moles of Cl atoms in MgCl2 from the formula units given, we use the Avogadro's number that relates the number of moles to the number of units of an atom. Calculation is as follows:

2.41*10^24 formula units MgCl2 (1 mol MgCL2 / 6.022 x 10^23 formula units MgCl2) (2 mol Cl / 1 mol MgCl2) = 8.004 mol Cl
