To Calculate: The mass of
Explanation of Solution
Given:
The activity of
Formula Used:
Activity is related to decay constant as follows:
Here, N is number of atoms.
For radioactive decay, order of the reaction is first order thus,
Here,
Calculations:
Combining equation (1) and (2),
Putting the values,
Or,
Thus, the number of
For 1 mol, there are
Molar mass of
Therefore, the mass of
Now, the mass of
Therefore, the mass of
Conclusion:
Thus, the mass of
