If a sample is 10740 years old and has 400 atoms how many atoms are there after the organisms died?
After 10740 years, half of the sample would have decayed, so there would be 200 atoms left. If the original sample had 400 atoms, then there would be 200 atoms left in the sample after 10740 years.

How much carbon-14 would be left after 5700 years?
Carbon-14 has a half-life of approximately 5,700 years, meaning that after this period, half of the original amount of carbon-14 will have decayed. Therefore, if you start with a certain amount of carbon-14, after 5,700 years, you would have 50% of the original amount remaining. After another 5,700 years (a total of 11,400 years), 25% would remain, and so on. Thus, after 5,700 years, you would have half of the initial carbon-14 quantity left.
