What is the age of a mineral that contains 25 percent parent and potassium 40 and argon 40 and 75 percent daughter and the half life potassium 40 is 1.25 billion years?
The age of the mineral can be estimated using the ratio of parent to daughter isotopes. With 25% parent (K40) and 75% daughter (Ar40), this would correspond to three half-lives since 25% is reduced by half three times to reach 75%. Given the half-life of K40 is 1.25 billion years, the age of the mineral would be approximately 3.75 billion years old.
Yellow gold contains 10 percent the other metal?

Is soil pore contains mineral matter. if yes then how many percent are there?
Soil pores contain mineral matter along with organic matter, air, and water. The percentage of mineral matter in soil pores varies depending on the soil type and composition, but typically ranges from 40-60%. This mineral matter contributes to the physical structure and nutrient content of the soil.
What mineral does Minnesota produce 70 percent of?
iron ore
How old is a mineral that contains 25 percent U-235?
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).
