Suppose you found a material in which 12. 5% of the original radioactive atoms were present. If the half-life is 47 years, how old is the material?

Answer :

NAMRATA421GO

The response dates back 141 years. The formula (1/2)n = x can be used to compute it. x is the remaining fraction, There are n half-lives in total.

How do you determine a radioactive substance's half-life?

The amount of time needed for the reactant concentration to drop to half its initial value is known as the half-life of a reaction. A first-order reaction's half-life is a constant that is correlated with its rate constant radioactive atoms: t1/2 = 0.693/k.

How many half life does it take for a radioactive substance, such as a 1 C 3 b2 D 4, to decay to 12.5 percent of its initial volume?

The period of time it takes for half of the atoms in a given sample to experience radioactive, or nuclear, decay, is known as the half-life of a radioisotope.
