Question

If 96 grams of carbon-14 are originally present in a fossilized plant at the present time, how much will remain after 17,000 years? (The half-life of Carbon-14 is 5730 years.) Use the exponential decay model for Carbon-14: A=Aoe^(-.000121)t

Answer 1

well, you already have the decay model, so just plug that in

$\bf A=96e^{-0.000121\cdot 17000}\implies A=96e^{-2.057}$
