Explain living carbon samples the campfire made

Reference no: EM13181986

If 4.58g of the CaCO3 had a radioactivity of 1.57 d/min, how long ago (in years) was the campfire made? Recall "living" carbon samples show 15.3 d/min*g (carbon). note: CaCO3 is 12.00% carbon, and 14C has a half-life of 5730yr.
