Question

A fossil is found to have a 14^C level of 89.0% co

science physics

Answer 1

Answer #1

solution:

Half life of 14C = 5730 years

(1/2)^(x/5730) = 0.89
(x/5730) log (0.5) = log (0.89)
x/5730 = log (0.89) / log (0.5)
x = 5730 log (0.89) / log (0.5)

x = 963.34 years

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)
