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

 a. 1.3  1016 Bq
  c. 3.6  1014 Bq
  b. 1.1  1015 Bq
  d. 3.2  1015 Bq

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
