The age of the given rock is 700 million years.
The given parameters;
- <em>original mass of the rock, = 20 g</em>
- <em>mass of the rock remaining after decay, = 10 g</em>
- <em>half life of Uranium, </em>
<em> = 700 years</em>
age of the rock ----------------------------- mass remaining
0 
------------------------------------------- 20 g
1 half life (
) ------------------------------ 10 g
Age of the rock 
Thus, the age of the given rock is 700 million years.
