: Question 6 The Isotope 65ga Undergoes Radioactive Decay With Decay Constant I 0 0456 Min What Is The Half Life Of 65 2 (26.27 KiB) Viewed 76 times

Question 6 The isotope 65Ga undergoes radioactive decay, with decay constant i = 0.0456/min. What is the half-life of 65Ga? min How long will it take for 60.0% of a sample of 65Ga to decay? min What is the activity (rate of decay) for 8 mg Ga-65, in decays/second? decays/s

Question 7 a Carbon from a glacier mummy discovered in the Tyrolean Alps has an activity of 7.63 decays of Typenumbu 8 points 14C per minute per gram of carbon. If carbon from a living organism in this region has an activity of 14.9 decays/min/g C, estimate the age of the mummy. (The half-life of 14C is 5730 years.) age= years old
