Question 941762: Consider that the half-life of Polonium-210 is 140 days.
10. What approximate daily percentage of decay does Polonium-210 demonstrate?
% (Round to two decimals.)
(Hint: use the Rule of 70 backwards by dividing by the half-life period instead of the rate.)
11. What percentage of the original amount of Polonium-210 would be left after 525 days of decay?
% (Round to two decimals.)

What is the rule of 70?
Use the half-life to find the decay constant in .
You know that ,
-----reminder, this is exponential. No average makes sense here, unless for some limited time period.
