This Question: 1 pt 20 of 20 (15 complete The half-life of carbon-14 is 5730 years. How long does it take for 2.2 grams of carbon-14 to be reduced to 0.2 grams of carbon-14 by radioactive decay? (Do not round until the final answer. Then round to the nearest hundredth as needed.) Enter your answer in the box
The half-life for the radioactive decay of C-14 is 5730 years. How long will it take for 25% of the C-14 atoms in a sample of C-14 to decay. If a sample of C-14 initially contains 1.5 mmol of C-14, how many mmols will be left after 2255 years.
The half-life for the radioactive decay of C−14 is 5730 years. A) How long will it take for 30% of the C−14 atoms in a sample of C−14 to decay? B) If a sample of C−14 initially contains 1.9 mmol of C−14, how many millimoles will be left after 2280 years?
1. The half-life of carbon-14 is 5730 years. A sample is found to have one-eighth the original amount of carbon-14 in it. How old is the sample? 5730 years, 716 years, 45800 years, 17200 years 2. Why wouldn't you use carbon-14 dating on a piece of shell that was estimated to be 1 million years old? Sea shells do not have radioisotopes, carbon dating is only useful on plants, uranium dating is better for items older than 1/2 million years,...
please explain too 1) There is 1.3 radioactive carbon-14 atoms for every trillion carbon atoms in living organisms. Carbon-14 beta decays to nitrogen-14 with a half-life of 5730 years. (a) What is the activity due to carbon-14 in a 5o kg person? (Assume that 18% of the mass is carbon.) (b) Calculate Q for the decay. (c) what is the annual radiation done that a pernon e.eives fion their own arn-ht thenua C 14.003242 u N 14.003074 u 1) There...
