The half-life of Carbon-14 is 5730 years. Suppose a fossil is found with 50% of Carbon-14 as compared to a living sample. How old is the fossil? (would the answer be 5730?)

Vocaloid:
Yes, that's correct. The half life is the time it takes for a substance to decay by 50%, so an object with 50% of its carbon-14 would be 5730 years old.
