Answer:
46.8% should be. correct, I'm not fully sure though. : )
The more water added the lower the conductivity. The Na+ and Cl- ions allow the solution to be conductive. The lower the concentration, the less conductive the solution will get until it is not conductive at all.
Calcium chloride has the following formula: CaCl2
Based on this formula: one mole of calcium chloride contains two moles of chlorine
Therefore: two moles of calcium chloride would contain four moles of chlorine.
Number of atoms = number of moles x Avogadro's number
Number of atoms = 4 x 6.022 x 10^23 = 2.4088 x 10^24 atoms
