10 Half Life Problems And Answers Examples - edutized.com Answer 1. A radioisotope decays from 150 mg to 120.2 mg in 5 days. Calculate the half-life of this isotope. Solution From N t = 1 2 t t 1 / 2 N o we rearrange this equation to take the form t 1 / 2 = t log 2 log N o N t = 5 log 2 log 150 120. 2 = 15.6482 days 2. Iodine-131 has a half-life of 8 days.

Half-Life Data-Teacher Answer Key 1.Hypothesize what half‐lifeis: Half‐life is the amount of time it takes for approximately half of the radioactive atoms in a sample to decay intoa more stable form. Every radioactive element has a different half‐life. 2. Calculate thenumber of radioactive atoms remaining after each half‐life. PDF St. Francis Preparatory School Created Date: 4/13/2011 8:49:26 AM ChemTeam: Half-Life Problems #1 - 10 Problem #3: Os-182 has a half-life of 21.5 hours. How many grams of a 10.0 gram sample would have decayed after exactly three half-lives? Solution: (1/2) 3 = 0.125 (the amount remaining after 3 half-lives) 10.0 g x 0.125 = 1.25 g remain 10.0 g − 1.25 g = 8.75 g have decayed Note that the length of the half-life played no role in this calculation.
