To estimate the age of a mineral containing 25% U-235, we can use the half-life of U-235, which is about 703.8 million years. If the mineral has 25% U-235 remaining, it has undergone two half-lives (100% to 50% to 25%). Therefore, the mineral is approximately 1.41 billion years old (2 x 703.8 million years).
