a particular radioactive isotope has a half-life of 5.0 s. what fraction of the original amount of isotope will remain in a sample after 20.0 s?

samarium-146 (s146m) can decay to form neodymium-142 (n142d). each atom of s146mthat decays produces one atom of n142d and one alpha particle. if the mass of 1 mol s146mis 145.9130 g, the mass of 1 mol n142d is 141.9077 g, and the mass of 1 mol alpha particles is 4.0015 g, how much mass is lost during the decay of 1 mol s146m to n142d?
