Question

The half-life of carbon-14 is 6000 years. gow much of a 15g sample will remain after 1500 years

Answer 1

quantity remains, Nt = 12.613 grams

Explanation:

N(t) = N0(1/2)^(t/t1/2)

quantity remaining = initial amount * (1/2)^(elapsed time/half life)

quantity remaining = 15 * (1/2)^(1500/6000)

quantity remaining = 15 * (1/2)^(1/4)

quantity remaining = 15*.84089641525

quantity remaining = 12.6134462287
