PLEASE HELP ME ASAP I ONLY HAVE SUCH LITTLE TIME LEFT I ONLY NEED THE ANSWERS ITS OKAY IF THERES NO EXPLANATION

The decay chain of ununquadium-289 is shown below. 289 Uag + 112 2! Ds + Y 245 Uub + X 18 Ununquadium-289 has a half-life of 30.4 5. 18. The decay particles X and Y are a beta post narticle and an alpha acle, respectively both alpha particles an alpha part and a beta positive part spectively both beta positive particles Use the information from the above question to answer the following question. If 1.00 pig of ununquadium-289 is initially produced, the mass of ununquadium-289 remaining after 1 50 min will be 10.128 19 50.977 49 0.703 Ng 0 255 pg Mass of U-235 390.1729 x 10 27 kg Mass of Ba-140 232.25 x 1027 kg Mass of Kr-93 154.26 x 1027 kg Mass of neutron 1.6749 x 1027 kg 22.
