Archeologists have discovered a mummified corpse and they want to know how long ago she died. They determine that there is 25% C14 in her body. Use the reference diagram to determine how long ago she died. Explain your answer.

Answer 1

To determine the age of the mummified corpse, we can use the half-life of C14 to estimate when she died. Carbon-14 has a half-life of 5730 years, which means that after 5730 years, half of the original amount of C14 in a sample will have decayed.

Given that there is 25% C14 in the body of the mummified corpse, we can assume that the original amount of C14 would have been 100%. Since half of the C14 would decay every 5730 years, the remaining 25% of C14 corresponds to two half-lives of decay.

Therefore, we can calculate the age of the mummified corpse by multiplying 5730 years by 2 (the number of half-lives required to go from 100% to 25%):

5730 years/half-life * 2 half-lives = 11,460 years

Therefore, the mummified corpse died approximately 11,460 years ago.

Answer 3

The mummified corpse's age can be estimated using the amount of C14 remaining in her body. With 25% of C14 detected, it is assumed that the original amount was 100% and that two half-lives have passed to reach this level of decay. With a half-life of 5730 years for C14, the calculation shows that the mummified corpse likely died around 11,460 years ago.
