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)?
