Textbook Problem

Find the mass of 239Pu mat has an activity of 1.00 μCi.

To determine

The mass of the 239Pu .

Explanation

Given info:

The activity is

  A=1.00μ·Ci

Formula used:

The mass can be found as

  m=NNa×molarmass

Calculation:

The activity

  A=1.00μ·Ci=1.00×106×3.70×1010BqA=3.70×104Bq

Activity is defined as

  A=Nln2T 1 2N=AT1/2ln2

Substituting the values

  N=(2
