Q 3 Magnesium chloride (MgCl) is highly soluble in water. In North America, magnesium chloride is produced primarily from Great Salt Lake brine. Calculate attractive force (F.) in [N] between aMg¹ iron and Cl iron that is separated by an equilibrium distance r.. (the ionic radii of the ions are:= 0.072 nm and re" =0.181 nm) Express your answer in N in engineering notation to three significant figures. Do not include the units. Example: 5.28E-3
