Question 295010: /**************************************************/
How would you define / describe / calculate the following (you may want to draw a diagram if it is helpful):

  • A. The half-life (t1/2) of a drug
  • B. What (approximate) percentage of the drug remains after 3 half-lives?

Yes, I know that I can just write:

  • 1 = 100%
  • 2 = 50%
  • 3 = 25% & etc,
but what formula do I use to calculate it?
