The C-14 in an ancient scroll is 50% of that found in living organisms. What is the age of the scroll?

Interpretation Introduction

Interpretation:

The age of the given scroll is to be determined.

Concept introduction:

Carbon-14 dating is a type of analysis in which the objective age of a carbon-based material is determined.

The age of a scroll and a fossil can be determined with the help of carbon-14 dating.

Explanation of Solution

The table that shows the amount of carbon14 in a scroll is as follows:

Number of half-lives         %C-14        Age of fossil_            0                             100.0              0            1                              50.0             5,730           2                              25
