Cf-253 decays primarily by beta emission to yield Es-253. This process has a half-life of 17.81 days. Calculate the binding energy for Cf-253 if one atom of this nuclide has an atomic mass of 253.08249. Express your answer in units of picojoules/nucleus where 1 picojoule = 1x10-12 joule. [NOTE: Express your answer to 3 significant figures after the decimal point, e.g. 1.111]
