A 64-g sample of germanium-66 is left undistured for 12.5 hours. At the end of that period, only 2.0 g remain. What is the half-life of this material?

whereis the half-life

Take theof both sides. Note that this is an unusual base, but it simplifies the processing since
. You could use any logarithm base, but this makes the algebra easier.
there is one more way
calculate the number of atoms in 64g of germanium .This is u'r N0(pronounced as N not i.e initial no of atoms) Now calculate the number of germanium atoms in 2g Nt.
Now use the formula k=2.303 * log(No/Nt) / t where t-12.5 hrs
now t1/2 = 0.693/k
