Tritium (3H) has a half-life of 12.3 years and releases 0.0186 MeV energy per decay. What is the rate at which energy is released for a 3.0-gram sample of tritium? (NA = 6.02  1023 mol1, 1 year = 3.16  107 s, 1 MeV = 1.6  1013 J, and mt = 3.01605 u)
 a. 3.2 W
  c. 9.6 W
  b. 1.1 W
  d. 0.33 W

Question 2

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? (NA = 6.02  1023 mol1, 1 year = 3.16  107 s, 1 MeV = 1.6  1013 J, and mt = 3.01605 u)
 a. 1.3  1016 Bq
  c. 3.6  1014 Bq
  b. 1.1  1015 Bq
  d. 3.2  1015 Bq
