Wouldn't it have to assume that the object were 100% uranium to begin with?

They know how much uranium is usually on stuff and then start counting isotopes.

If it has more isotopes it means it's older. Facts.

But say a rock. WE know the half-life of Uranium. How do we know now much was originally in the rock?

Why would I want to date a chemical? Women are already toxic enough.

The rocks get more stable over time.

But wouldn't you have to know the original amount of uranium them to make that calculation?

No because they can see how much Lead is in it now.

How does that tell them anything? would it not have had to have been 100% uranium at first for that to matter?

There are other elements besides Uranium, you know. They know this from looking at rocks.
