Answer:
The radioactive isotopes within these brains typically record the ages of the grains-not the time when the sedimentary rock was formed, making it difficult to date using radiometric dating. The half-life of U-235 is 704 million years.

hope this helps but if i'm wrong then i'm sorry..
Answer:

Explanation:
Hello,
In this case, during titration at the equivalence point, we find that the moles of the base equals the moles of the acid:

That it terms of molarities and volumes we have:

Next, solving for the volume of lithium hydroxide we obtain:

Best regards.
There are 69 moles in 376.2 g s
