Problem Details

The following plot shows the potential energy of two Cl atoms as a function of the distance between them.

A line graph has Cl-Cl distance (angstroms) on the X-axis, ranging from 0 to 6.0 with intervals of 2.0, and energy (kilojoules per mole) on the Y-axis, ranging from -300 to 200 with intervals of 100.  The line appears asymptotic to an energy of 0 as the distance increases beyond 6 angstroms. The following data values are approximate: Cl-Cl distance of 0.5 angstroms correlates to an energy of 100 kJ/Mol; 1 angstrom and -100 kJ/Mol; 2 angstroms and -230 kJ/Mol; 3 angstroms and -170 kJ/Mol; 4 angstroms and -85 kJ/Mol; 5 angstroms and -20 kJ/Mol; 6 angstroms and -20 kJ/Mol.

We know that the Cl2 molecule exists. What is the approximate bond length for the Cl-Cl bond in Cl2 from this graph?
