researchers find a fossil of a large ma
Researchers find a fossil of a large mammal that contains one-sixteenth the amount of carbon-14 that is preset in living organisms. Using carbon-14 dating, about how old is this fossil? Recall that carbon-14 has a half-life 01 5730 years. 11,460 years 17,190 years 22,920 years 91.680 years

v The cloth shroud from around a mummy is found to have a 14Cactivity of 10.5 disintegrations per minute per gram of carbon as compared with living organisms that undergo 16.3 disintegrations per minute per gram of carbon. You may want to reference (Pages 913 - 916) Section 21.4 while completing this problem. Part A From the half-life for 14C decay, 5715 yr, calculate the age of the shroud. Express your answer using two significant figures.
