Q7. An artifact has a carbon-14 decay rate of 8.55 disintegrations per minute per gram of carbon (8.55 dis/min.g C). Living organisms have carbon-14 decay rate of 15.3 dis/min.g C. How old is the artifact? (The half-life of carbon-14 is 5715 yr.) a) 4.81 x 10 yr b) 2.10 x 10'yr c) 3.20 x 10 yr d) 1.21 x 10yr
