Consider the fission of `""_(92)^(238)U` by fast neutrons. In one fission event, no neutrons are emitted and the final end products, after the beta decay of the primary agments, are` ""_(58)^(140)Ce and ""_(44)^(99)Ru` Calculate Q for this fission process. The relevant atomic and particle masses are
`m( ""_(92)^(238)U ) =238.05079 u`
`m( ""_(58)^(140)Ce ) =139.90543 u`
`m( ""_(44)^(99)Ru ) = 98.90594 u`
