The half-life of carbon-14 is 5730 years. If we start with 10 grams of carbon-14, after 5730 years, we will have _____ of carbon-14 left.

5 grams. Think.

To determine the amount of carbon-14 left after a certain time, we can use the concept of exponential decay. The half-life of carbon-14 is 5730 years, which means that after this period, the amount of carbon-14 is reduced by half.

In this case, we start with 10 grams of carbon-14. After one half-life (5730 years), half of the carbon-14 will remain, which is 5 grams. After another half-life (5730 years), half of the remaining 5 grams will remain, which is 2.5 grams. This process continues infinitely, with the amount decreasing by half after each half-life.

So, after 5730 years, we will have 5 grams of carbon-14 left.
