The radiocarbon content of 14C decreases after the death of a living system with a half-life of 5730 years. If an archaeologist working a dig finds an ancient firepit containing some partially consumed firewood and the wood contains only 12.5 percent of the 14C content of an equal carbon sample from a present-day tree, a) the current rate of decay is 368 decays/minute. What is the mass of 12C in the sample at the time of the discovery?
