WebAug 13, 2024 · The second half-life has an activity of half the previous count (not the initial count). Equation 11.2.1 can be used to calculate the amount of radioactivity remaining after a given time: N t = N 0 × ( 0.5) number of half-lives. where N t = activity at time t and N 0 = initial activity at time t = 0. WebExample 2: Find the value of the decay constant of a radioactive substance having a half-life of 0.04 seconds. Solution: Given half life of the substance is t1 2 t 1 2 = 0.04. The half life formula can be used to find the half life of the substance. t1 2 t 1 2 = 0.693/ λ.

WebJun 21, 2024 · Solution. If we compare the time that has passed to the isotope’s half-life, we note that 44.0 s is exactly 4 half-lives, so we can use Equation 13.1.1 with n = 4. Substituting and solving results in the following: a m o u n t r e m a i n i n g = 5.00 g × ( 1 2) 4 = 5.00 g × 1 16 = 0.313 g. lifeline big book fair illawarraWebProblem #30: The isotope Ra-226 decays to Pb-206 in a number of stages which have a combined half-life of 1640 years.
