Refer to Figure 13-2 and determine how much parent material will be left after five half-lives.
THIS IS THE BEST ANSWER ๐
Explanation: This is a type of radioactive decay and the entire radioactive process follows first order kinetics.
Half-life is the time required to decompose half of the reactants. so after each half – life the reactant decomposes to half its present value.
Now, to calculate the number of half-lives, we use the formula:
where,
amount of reactant left after half – life.
= Let Initial amount of reactant = 100 g
number of half – lives
