Chapter 29, Problem 50P

(a)

To determine

The number of Carbon $\text{-14}$ atoms in a sample of $50\text{g}$ Carbon, if there is $1$ Carbon $\text{-14}$ atoms in ${10}^{12}$ Carbon atoms.

(b)

To determine

The decay rate of Carbon $\text{-14}$ atom, if the number of Carbon $\text{-14}$ atoms in a sample of $50\text{g}$ of Carbon $-12$ is $1$ per ${10}^{12}$ Carbon atoms.

(c)

To determine

The age of a buried tree, if the sample of $50\text{g}$ carbon containing Carbon $\text{-14}$ with a decay rate of $-2.2{\text{s}}^{-1}$.
