Interpretation:
The concentration of calcium ions in a sample of milk is to be determined and whether the given sample meets the concentrations, stated on a milk carton or not is to be predicted.
Concept Introduction:
For radioactive elements, the number of disintegrations per second is defined as an activity. Mathematically, it is represented as follows:
The activity is known to be proportional to the number of radioactive nuclei,
Here,
For the change in the number of nuclei per second:
The half-life for a first-order reaction is given as,
