Question

The amount of C-14 isotope in a piece of wood is found to be 1/16^th of its amount present in a fresh piece of wood. The age of wood, half-life period of C-14 is 5770 years, is ______ years.

Options

• 10000

• 23080

• 3526

• 40036

Answer 1

The amount of C-14 isotope in a piece of wood is found to be 1/16^th of its amount present in a fresh piece of wood. The age of wood, half-life period of C-14 is 5770 years, is 23080 years.

Explanation:

`"N"/"N"_0 = 1/16`

`(1/2)^"n" = (1/2)^4`

n = 4

Total time = n × t_1/2

= 4 × 5770

= 23080 years.
