Question

This exercise uses the radioactive decay model. The burial cloth of an Egyptian mummy ts estimated to contain 57% of the carbon-14M it contained originally. How long ago was the mummy buried? (The half-life of carbon-14 is 5730 years Round your answer to the nearest ten years) A wooden artifact from an ancient tomb contains 55% of the carbon-14 that is present in hiving trees How long ago was the artifact made? (The half-fife of carbon-1 5730 years. Round your answer to the nearest whole number.)yr This exercise uses the radioactive decay model.

Explanation / Answer

0.55 = 0.5^(t/5730) where t = years to get to 55%

log both sides
log 0.55 = (t/5730) log 0.5

divide both sides by log 0.5 and multiply by 5730 we get
t = 5730 log 0.55 ÷ log 0.5=4942.10=4942years
