Question #200408

Suppose a piece of cloth was found to contain a third of its original C-14/C12

ratio, what is the approximate age of the sample? State any assumptions you

made during calculation.

Expert's answer

answer; * age of sample is 8844 years.*

Let,

be new ratio

sol.

but we know that is stable isotope,

therefore,

we get,

*we have half life of C*^{14}* as = 5580 years*

..............................1

now using,

we get,

...............................2

using 1 and 2 we get,

*therefore age of sample is 8844 years.*
