How to figure out the half-life if 10% of the sample decayed each day. 1000x .10 = 100 - 1000-100 =900 and so on...If we continue this trend, we will notice around day 6 and 7 we reach half-life (500)
5- Is there an equation to this?
No!Phone's
4 - Alright let's focus on percentage because dividing the same number over and over is simple6- Yes, .693 / ln (1000/900) = 6.5774This same method would work with 20% too.That's it, be sure to study.
