Question

If the half life of pb-210 is 22 years. How much of the original amount of pb-210 remains after 88 years

Answer 1

This should be posted under the chemistry tab as people there may understand this better. if I have this right though, it should go from origional, to half, to a quarter, to an eigth, to a sixteenth. so the answer is 1/16 of the origional.
