Question
Plutonium-238, an α emitter and a compact heat source, has a half-life of 86 years. Coupled with a PbTe thermoelectric device, it is used as a very reliable electrical energy source for cardiac pacemakers. If 100.0 grams of 238Pu (238.0495 g/mol) were used in a pacemaker, how many α  particles would it produce in 10 years? (1 mole =  6.02 ×  1023  atoms)

A. 6.02 ×  1023
B. 3.01 ×  1023
C. 3.01 ×  1022
D. 2.33 ×  1023
E. 1.96 ×  1022
