(a)
To Find: The initial mass of the sample.
(a)
Answer to Problem 100RE
Explanation of Solution
Given The half-life of the palladium-
Formula used:
Given:
Then
Relative decay rate is
So to find the initial mass of the sample solve the equation
Hence, initial mass of the sample is
(b)
To Find: The function that model the mass remaining after
(b)
Answer to Problem 100RE
Explanation of Solution
Given The half-life of the palladium-
Formula used:
Using the radioactive model
So the function will become
(c)
To Find: The mass after
(c)
Answer to Problem 100RE
Explanation of Solution
Given The half-life of the palladium-
Formula used:
Using the function
For the mass after
Then
Hence, the mass after
(d)
To Find: The time when the remaining mass is
(d)
Answer to Problem 100RE
Explanation of Solution
Given The half-life of the palladium-
Formula used:
Using the function
For The time when the remaining mass is
Then
Hence, the time when the remaining mass is
