In a certain hypothetical radioactive decay process, species A decays into spesies `B` and species `B` decays into` C` according to the reactions
`{:(A rarr 2B +"particles +energy"),(B rarr 2C+"particles +energy"):}`
The decay constant for species `B` is `lambda_(2)=100 s^(-1)`. Initially, `10^(4)` moles of species of `A` were present while there was no none of `B` and `C`. It was found that species `B` reaches its maximum number at a time `t_(0)=2 1n(10)s`. Calcualte the value of maximum number of moles of `B`.
