Textbook Problem

(a) Calculate the energy released in the a decay of 238U.

(b) What fraction of the mass at a single 238U is destroyed in the decay? The mass of 234Th is 234.043593 u.

(c) Although the fractional mass loss is laws for a single nucleus, it is difficult to observe for an entire macroscopic sample of uranium. Why is this?

To determine

(a)

The energy released in the a decay of U238 ?

Explanation

Given info:

   m( U 238 ) = 238.05078826u

   m( T 234 h)=234.043601u

   m( H 4 e)=4.002602u

Formula used:

Energy,

  E=Δmc2

Calculation:

We have the equation,

  U

To determine

(b)

What fraction of the mass of a single U238 is destroyed in the decay? The mass of T234h is 234.043593 u?

To determine

(c)

Why although the fractional mass loss is large for a single nucleus, it is difficult to observe for an entire macroscopic sample of uranium?
