Problema Solution

the half life of radioactive carbon-14 is 5700 years. how much of an initial sample will remain after 3000 years?

Answer provided by our tutors

the model for radioactive decay is:


A(t) = A0 (1/2)^(t/h)


A0 = is the initial sample


h = 5,700 years the half-life


t = 3,000 years


A = A0(1/2)^(3000/5700)


A = A0 * 0.6943


after 3000 years 69.43% of the intial amount will remain.
