Problem: A certain radioactive nuclide has a half-life of 3.00 hours.b. Calculate the decay rate in decays/s for 1.000 mole of this nuclide.

FREE Expert Solution

Recall the equation for a first-order half-life:

t12=ln 2k


t1/2 = 3.00 hr


Calculate k:

t12=ln 2kk=ln 2t12k=ln 23.00 hr×1 hr60 min×1 min60 s

k = 6.418x10-5 s-1


Calculate rate:
