Two new metallic elements have been discovered, Cimium (Ci) and Sadowium (Sd). Both the pure elements and their solutions form simple cubic lattices. The bond strengths of the Ci-Ci and Sd-Sd bonds are known, but not the Ci-Sd bond.

Bond Bond Energy (kJ/mole)

Ci-Ci -245

Sd-Sd -191

J-R ??

Mixing a solution of 40% cimium and 60% sadowium is an endothermic process. According to your calorimeter, the solution draws 44.6 kJ/mol of heat when mixed. What is the strength of the Ci-Sd bond? Please give your answer in kJ/mol.
