What is the age of a prehistoric mummified human skin that contains 12.5 percent of the original amount of carbon-14?

The half life of C-14 is about 5730 years and 12.5% is 100% x (.5)^3 so 3 half lives of the C-14 have occured. Now all you do is multiply 5730 years by 3 and get 17190 years. That's pretty old!

The age of the mummified human skin can be determined using the concept of carbon-14 dating. By comparing the remaining amount of carbon-14 in the sample to the initial amount, scientists can estimate the age. Given that the sample contains 12.5 percent of the original carbon-14, scientists can calculate the approximate age based on the known decay rate of carbon-14.

An artifact is found that some are claiming is 30000 years old 3.1 percent of the original carbon14 is present The halflife of carbon14 is 5730 year?
To determine the age of the artifact, you can use the formula for exponential decay of radioactive elements: (N = N_0 \times (1/2)^{t/T}), where N is the final amount (3.1% of the original), N0 is the initial amount (100%), t is the time passed, and T is the half-life (5730 years). By substituting the values, you can solve for t, which will give you the age of the artifact.
Why is an original material fossil so valuable to a paleontologist?
An original material fossil is valuable to a paleontologist because it provides direct evidence of the ancient organism without alteration or interpretation. It allows researchers to study the physical characteristics, biology, and environment of the organism with greater accuracy. Original material fossils are rare and can provide unique insights into our understanding of prehistoric life.
Who leather contains most natural grains?
Full-grain leather contains the most natural grains as it is made from the top layer of the hide, retaining the original texture and markings. This type of leather is known for its durability and unique appearance due to the natural grain patterns.
What is the liquid in the beaker called after filtering?
The liquid in the beaker after filtration is called the filtrate. It is the liquid that has passed through the filter and contains the dissolved or suspended components that were separated from the original mixture.
How can a rock be made from the remains of an animal?
When an animal dies, its remains can undergo a process called fossilization where its tissues are gradually replaced by minerals. Over time, this can result in the formation of a rock-like structure called a fossil. The fossil preserves the shape and structure of the original organism and provides valuable information about prehistoric life.
Mummified animals found in dry caves can be examples of fossils with?
exceptional preservation of soft tissues due to the arid environment.

What percent of carbon14 is left after 5 half-lives?
After 5 half-lives, 3.125% of the original carbon-14 would remain. Each half-life reduces the amount by half, so after 5 half-lives, it would be reduced by a factor of 2^5 = 32.
