Hi,
Hope you are doing well.
__________________________________________________________________________
Given that,
Initial mass of tritium, m = 10 kg = 104 g
Molar mass of tritium, M = 3 amu= 3 g/mol
Therefore, initial no.of moles of tritium is given by,
Therefore, Initial no.of atoms:
Also, given that, Half life of tritium,
Therefore, Initial rate is given by,
Therefore, The correct option is Option (d) 3.6 x
1018 decays/s
Best of luck for your
finals!
