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 primay fragments, 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`
