One pathway for the decay of 26 Al is positron emission to form 26 Mg. The half-life

Question:

One pathway for the decay of ²⁶Al is positron emission to form ²⁶Mg. The half-life of ²⁶Al is 7.17 × 10⁵ years.

(a) How many ²⁶Al nuclei would decay per second in a 1-mol sample of ²⁶Al?

(b) The mass of ²⁶Al is 25.986892 u, the mass of ²⁶Mg is 25.982593 u, and the mass of a positron is 5.486 × 10^–4 u. What is the energy released in a single ²⁶Al decay event?

(c) If all the energy released is assumed to be heat, how much heat is evolved in one minute by the decay of the 1-mol sample of ²⁶Al from part (a)?
