The dose I was given is -younger copy of an earlier document (in which case it is odd that there are no references to it in other documents, since only famous works tended to be copied), or, which is more likely, this is a recent forgery written on a not-quite-old-enough ancient parchment.

However, I note that there is no beginning or ending amount given.

I missed my science radioactive **dating** notes, and I haven't a clue **how** to figure my homework out. There are 5 questions, so I'm asking only for one question's answer, and **how** you **solved** it so I can figure out the rest. Now putting those words into the master formula above y = 1/2, y initial = 1, t = half-life = 5700 years 1/2=1e^(5700r) from this, you get that r = ln(1/2)/5700 = so what we've done so far is simply use the half-life info to get "r" when **carbon** radioactively decays, it will go down one on the periodic table to nitrogen.

that's all the theory that you need to know, and now onto the **problem** whenever you are given a half-life, you need to use the half-life to find "r" say you initially have 1 mole, then when a time elapses that is equal to the half-life, you will have half of the initial one mole remaining.

Give an interval for the possible ages of the bone.

see, i told you it didnt give many details, i looked up **carbon** **dating** on google and it said the approx.

Let A be the amount of *carbon*-14 present at any instant 't'.

So, -d A/dt is directly proportional to A d A/dt = -k A,where k is the decay constant.

alright, so there was this question in my math book, doesn't give many details, thats why i found it confusing...debating whether or not to post this question in chem.
