The statement 2+2=4 would be considered a LAW in the science world
Answer: It was obtained 8515 years ago

t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
a) to find the rate constant:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.


b) for completion of 36% of reaction
