Tritium (³H)has a half-life of 12.3 years and releases 0.0186 MeV energy per decay.What is the activity of a 9.0-gram sample of tritium? (N_A = 6.02 × 10²³ mol^-1,1 year = 3.16 × 10⁷ s,1 MeV = 1.6 × 10^-13 J,and m_t = 3.01605 u)

Question

Quizplus · Accepted Answer

The activity (A) is calculated using A = λN, where λ = ln(2)/half-life. First, calculate the number of moles of tritium, then the number of atoms (N) using Avogadro's number. Convert the half-life to seconds and calculate λ. Finally, calculate the activity in Bq.
