Learn the formula for half life as well as see an example in this free math video tutorial by Marios Math Tutoring009 Formula for Calculating Half Life03. Indium-112 has a half life of 144 minutes. T 1 2 ln 2 k displaystyle t_ 12 frac ln 2 k The half-life of a first order reaction is independent of its initial concentration and depends solely on the reaction rate constant k.

Represents the half-life of the decaying quantity t is a positive number and is the mean lifetime of the decaying quantity l is a positive number and is certainly the decay constant of the decaying quantity.

The ln 2 stands for the natural logarithm of two and can be estimated as 0693 and the l is the decay constant. And so How to Calculate Half Life. The formula for a half-life is T12 ln 2 l. And half-life tells us that after 5730 years well have 12 of our initial sample left.
