Plutonium-238 Is An $\alpha$ Emitter and a Compact Heat Source $\alpha$ Particles
Would It Produce in 10 Years?
A) 6

Plutonium-238 is an $\alpha$ emitter and a compact heat source. Coupled with a PbTe thermoelectric device, it is used as a very reliable electrical energy source for cardiac pacemakers. It has a half-life of 86 years and an atomic weight of 238.0495 g/mol. One mol is equal to 6.02 * 10²³ atoms. If 100.0 grams of ²³⁸Pu were used in a pacemaker, how many $\alpha$ particles
Would it produce in 10 years?

A) 6.02 * 10²³
B) 3.01* 10²³
C) 3.01 * 10²²
D) 1.96 * 10²²
E) 2.33 *10²³
