## Specific Activity of Isotope Solution

STEP 0: Pre-Calculation Summary
Formula Used
Specific Activity = (Activity*[Avaga-no])/Atomic Weight of Nuclide
As = (λ*[Avaga-no])/M
This formula uses 1 Constants, 3 Variables
Constants Used
[Avaga-no] - Avogadro’s number Value Taken As 6.02214076E+23
Variables Used
Specific Activity - (Measured in Becquerel per Kilogram) - Specific Activity is defined as the concentration of the radioactivity or the relationship between the mass of radioactive material and the activity.
Activity - (Measured in Becquerel) - Activity of Radioactive Substance is the Number of atoms disintegrated in unit time. It is also called as the rate of disintegration.
Atomic Weight of Nuclide - (Measured in Kilogram) - Atomic Weight of Nuclide is defined as the total number of protons and neutrons in the nucleus of an isotope of the nuclide.
STEP 1: Convert Input(s) to Base Unit
Activity: 0.0011 Disintegrations per Second --> 0.0011 Becquerel (Check conversion ​here)
Atomic Weight of Nuclide: 125 Atomic Mass Unit --> 2.07567525023271E-25 Kilogram (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
As = (λ*[Avaga-no])/M --> (0.0011*[Avaga-no])/2.07567525023271E-25
Evaluating ... ...
As = 3.19142160376838E+45
STEP 3: Convert Result to Output's Unit
3.19142160376838E+45 Becquerel per Kilogram -->3.19142160376838E+42 Becquerel per Gram (Check conversion ​here)
3.19142160376838E+42 3.2E+42 Becquerel per Gram <-- Specific Activity
