The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass.
Starting with 155 grams of a radioactive isotope, how much will be left after 3 half-life's?
Round to the nearest gram.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It will be after the first half-life,
after the second half-life, and
after the third half-life.
