half life of tritium over time will decay by emitting energy into the environment in the form of radiation and the amount will be halved in 12.43 yaers. A group of scientists started observing in 2 separate containers, A and B, carrying unknown tritium from Jan 1, 1953. General formula for half life is N(t)=No(1/2)^t/x where N(t) is the final amount t years after, No is the initial amount of radioactive material, x is the half life and t is time.

a) what is the year the scientists would observe 12 g of tritium in container A?

b) what is the rate of change of amount of tritium when there is 1 g of tritium in the container? would the tritium ever disappear completely from the container? justify.

Thanks
