Question

A researcher claims that an ancient scroll from Greek scholars in about 500BCE. A measure of its carbon-14 decay rate gives a value that is 89% of that found in living organisms. How old is the scroll? (The half live of carbon14 is 5730 years). Express time in years as an integer A researcher claims that an ancient scroll from Greek scholars in about 500BCE.

Explanation / Answer

The given data:

% i =89%

solve for the age

The formula is given as follows (only applicable for Carbon)

age = ln(%left/100) / ln(1/2) * 5700

age = ln(89/100) / ln(1/2) * 5700 = 0.1681*5700 = 958.3 years

age =  958 years
