What is the age of a meteorite if potassium-40 decayed from 80 g to 10 g? The half-life of potassium-40 is 1.3 billion years. 1.
vekshin1

Answer:

3.9 billion years

Explanation:

The half-life of potassium-40 is the time it takes for half of it to decay.  

After one half-life, half of the original amount will remain.  

After a second half-life, half of that amount will remain, and so on.  

We can construct a table as follows:  

\begin{array}{cccc}\textbf{No. of} &\textbf{Fraction} &\textbf{Mass}\\ \textbf{Half-lives} & \textbf{Remaining} & \textbf{Remaining/g}\\0 & 1 &80\\\\1 & \dfrac{1}{2} &40\\\\2 & \dfrac{1}{4} & 20\\\\3 & \dfrac{1}{8} & 10\\\\4 & \dfrac{1}{16} & 5\\\\\end{array}

We see that the mass will drop to 10 g after three half-lives.

  1 half-life = 1.3 billion years

3 half-lives = 3.9 billion years
