![]() There are many parameters for the calculation of half-life and the calculation is also complicated. The half-life is calculated by comparing the initial amount and the amount of the substance after time t. The half-life of a substance is calculated to determine the age of the radioactive specie. So, the half-life calculator is here to help you with your half-life calculations. The calculation of half-life is a complicated task and many of us find it very difficult also. The half-life of the above substance is 0.7s. Then calculate the half-life of the substance. Suppose the decay constant of a substance is 0.96s -1. 0 is the initial amount of reactant, and is the rate constant. The half-life of a chemical reaction is also determined by using the reaction orders. Another formula to calculate the half-life can be written as ![]() The value of the decay constant is different for different substances. ![]() is the mean lifetime of the substance and ƛ is the decay constant. There are some other parameters available to calculate the half-life of a substance. t / t 1/2 is also denoted by n and it is the number of half-lives. N(t) is the amount of the substance after time t, N 0 is the initial amount of substance, t is the time elapsed, and t 1/2is the half-life of the substance. The half-life is calculated by calculating the remaining amount of the element after time t.
