Which halflife formula is correct?
Al = Ao(1/2)^(t/h)
Al = Ao(1/2)^(h/t)
where Ao =original amount
Al = amount left

Well, what do YOU think? Suppose t were equal to 2h.
The first formula gives AI= Ao(1/2)^(2h)= Ao((1/2)^h)^2 which is less than the amount at the half life.
The second formula gives AI= A0(1/2)^(h/2)= A0((1/2)^h)^(1/2) which is more than the amount at the half life.
If you let this (radioactive subtance?) sit longer, will it gain or lose mass?
