Question

A tree was cut down and used to make a statue 2300 years ago. What fraction of 14C that was present originally remains today? t½ of 14C is 5730 yr

Answer 1

0.76

Step-by-step explanation:

N = No(0.5)^t/t1/2

N/No = (0.5)^t/t1/2

t = 2300 years, t1/2 = 5730 years

N/No = (0.5)^2300/5730 = 0.5^0.401 = 0.76
