Given information
Given that half-life of the cesium- is years and the mass of a sample .
Calculate the mass that remains after years.
Step-by-step explanation
Step 1.
Let be the function of decay, where is the initial sample,
Thus, the expression for the mass remaining after days is given by
Given the half-life of cesium- is
Substitute the above values
