Question 2 Type numbers in the Beginning with 1.00 g of a sample of an unknown radioactive isotope, 0.07483 g of the isotope will remain after 145,000 years. What is the half-life of the isotope? 10 points yr
Question 5 A team of scientists found a wooly mammoth under the ice in Siberia and decided to use C-14 Type numbers in the boxes, dating to determine how long ago it lived. The initial activity of C-14 is 18.6 10 points disintegrations/min/g of carbon. Currently, the decay rate is 3.40 disintegrations/min/g of carbon. The 12 life of C-14 is 5730 years. How long ago did the mammoth live? yrs
