I have no idea how to do this Half life stuff please help!
If you sampled/tested a rock and found it to be 24% Lokium (and 76% DOL), how old would you estimate that rock to be?
Lokium? ... DOL? ... half-life?
need a few more details ...
To estimate the age of a rock based on the percentage of a radioactive isotope, you need to know the half-life of that isotope and make assumptions about the initial composition of the rock.
Let's assume the half-life of Lokium is 100 million years, and initially, the rock contained only Lokium (100% Lokium) with no DOL. Now, let's walk through the steps to estimate the rock's age:
Step 1: Determine the number of half-lives:
To determine the number of half-lives passed, you need to use a logarithmic equation. The formula to calculate the number of half-lives is:
Number of half-lives = log[Final Amount / Initial Amount] / log(0.5)
In this case, the final amount of Lokium is 24%, while the initial amount was 100%. Plugging these values into the formula:
Number of half-lives = log(0.24 / 1) / log(0.5)
Step 2: Calculate the age of the rock:
Now that you have the number of half-lives, you can calculate the age of the rock using the formula:
Age = Number of half-lives * Half-life of Lokium
Assuming the half-life of Lokium is 100 million years:
Age = Number of half-lives * 100 million years
By following these steps, you can estimate the age of the rock based on the given information.
