The largest fusion bomb ever detonated (called the Tsar Bomba) was tested by the Soviet Union in 1961. The explosion from the device released an energy of approximately 2.4e+17 J.
(a) How many kilograms of matter were converted to energy?
kg
(b) If this bomb used the deuterium-deuterium fusion reaction (Example 30.7), how many kilograms of deuterium were required?
