WebHalf-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value. The term is most commonly used in relation to atoms undergoing radioactive decay, but can be used to describe other types of decay, whether exponential or not. One of the most well-known applications of half-life is carbon-14 dating. WebSorted by: 9. Both approaches are correct. Avogadro's number is 6.02214129 × 10 23 and represents the number of carbon-12 atoms in 12 grams of unbound carbon-12 in the ground electronic state. 12 grams / 6.02214129 × 10 23 = 1.9926467 × 10 − 23 grams.
