Using your radioactive isotope half-life and decay constant (you solved for in question 4), solve the following scenario. A bone fragment was discovered on the grounds of VC, and the fragment was found to contain 12 grams of your isotope. In its original state, this same item would contain 315 grams of your isotope. How old is this fragment? Solve for time. The video gives an example starting at 10:18. Show all algebraic steps to solve this problem for t (time). Give the exact answer and the decimal approximation rounded to 2 decimal places. Be sure to label the unit of time (days, years, minutes, etc...)

Por 3. Each of you will be assigned a radioisotope. Look at the directions in the assignment in Canvas. Write that radioisotope and its' half life out here: Sodium-24 15 hrs N=Not 4. Using the formula illustrated in the video (around 4:30-6:30), find the decay constant for your radioisotope. Show all of your work, illustrating the algebraic process at which your decay constant was found. Give the exact value in natural logs and then give the approximate value (to the nearest 6 decimal places). ? =
