Plutonium-239 has been used as a power source for heart pacemakers. The chemical reaction taking place is
94239Pu⟶24He+92235U
Let the energy obtained from the following decay of 215 mg of plutonium-239 be A J.
Let B g be the minimum mass of Zn that would be needed for the standard voltaic cell
Zn ∣ ZnX2+ ∣∣ CuX2+ ∣ Cu
to obtain the same amount of electrical energy.
What is the value of 1000BA when rounded to the nearest integer?
Details and Assumptions
- Standard cell potential: Ecell∘=1.1 V.
- Atomic masses: He=4.0015 u,U=234.9935 u,Pu=239.0006 u.
