Half life

Determine the half-life of bismuth, when bismuth weight from the original weight of 32 g was only 2 grams in 242 minutes.

Final Answer:

t =  60.5 min

Step-by-step explanation:

m0=32 g m1=2 g q=1/2=21=0.5 T=242 min  m0    qT/t = m1 ln m0 + (T/t) ln q = ln m1  1/t= T lnqln(m1)  ln(m0)  t=ln(m1)ln(m0)T lnq=ln2ln32242 ln0.5=60.5 min
