Hi! I need some help in how to calculate when an isotope (Iodine 131I) has left 5% of its original mass, if the half-life period is 8 days.
By writing down on paper, I noticed that after 32 days, it will have 6.25% left of its original mass and after 40 days only 3.125%.
How do I count that though using a (simple) formula? When will it have 5% left of the original mass (100%) if the half-life period is 8 days?
Thank you!
