A radioactive with half life `T=693.1` days. Emits `beta`-particles of average kinetic energy `E=8.4xx10^(-14)` joule. This radionuclide is used as source in a machine which generates electrical energy with efficiency `eta=12.6%`. Number of moles of the nuclide required to generate electrical energy at an initial rate is `P=441 KW`, is `nxx10^(n)` then find out value of `(n)/(m) (log_(e )2=0.6931)N_(A)=6.023xx10^(23)`
