To calculate the number of moles of chlorine atoms in MgCl2 from the formula units given, we use the Avogadro's number, which relates the number of moles to the number of units of an atom. The calculation is as follows:2.41×10^24 formula units MgCl2 ( 1 mole MgCL2 / 6.022 x 10^23 formula units MgCl2 ) (2 mol Cl / 1 mol MgCl2) = 8.004 mol Cl
