Some fossil bones containing 1/32 of their original amount of carbon-14 are found. How many half-lives have passed? How old are the bones? (HINT: The half-life of carbon-14 is 5,730 years. If 1/8 of the original amount of carbon-14 was present, 1/8 = 1/23 or 1/(2x2x2), therefore 3 half-lives would have passed and therefore, the bones would be 5,730 years x 3 = 17,190 years old)

Without using a calculator, enter the correct value of 5-2 Express your answer to three significant figures or as a fraction. Radioactive substanoces follow a specific law of decay. Namely, if you have a sample of some radioactive isotope, the quantity left after a certain time, called the half-life and denoted 71/2 onehalf of what you had initially. If you wait a second hai-ife, then there will be half of what was left at the end of the first half-life....
