I can't figure this out , i've tried and tried but I was absent the day they explained this and I have no idea at all what decays/min is or any of that. I've solved 9 problems and I'm missing 4, and one of them is similar to this one that I will try to answer once you try explain this one to me.(adsbygoogle = window.adsbygoogle || []).push({});

Thank you very much!

1. The problem statement, all variables and given/known data

A 13.4756 g sample of petriﬁed wood was found in a petriﬁed forest. The sample showed a

C-14 activity of 11 decays/min.

How long has the tree been dead? The halflife of carbon-14 is 5730 years and freshly cut

wood contains 6.5 × 10^10 atoms/g of C-14 and there are 365.25 days in a year.

Answer in units of years.

2. Relevant equations

N=N0ek*t i think it's this? But I have no idea on how to use this

3. The attempt at a solution

I would try if I knew where to start lol
