Answer:
Explanation:
Given:
Initial mass of isotope (m₀) = 20 g
Half life of the isotope = (ln 4) years
The general form for the radioactive decay of a radioactive isotope is given as:
Where,
So, the equation is:
At half-life, the mass is reduced to half of the initial value.
So, at . Plug in these values and solve for 'k'. This gives,
Hence, the equation for the mass remaining is given as:
