The earth is about 4.5 × 10 9 years old. The half-life of uranium-238 is also about 4.5 × 10 9 years. This means that if a rock contained 100 g of uranium-238 at the time the earth came into being, then at the present time the rock would contain only half that amount, ½ × 100 = 50 g, of uranium-238.

Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960. It is based on the fact that radiocarbon (14

We even know that in a gram of carbon, 14 carbon-14 atoms turn into nitrogen every minute. (The 14 is a coincidence!). But the value that’s used to calculate the age of an object isn’t an absolute.
Stoichiometry / ˌ s t ɔɪ k i ˈ ɒ m ɪ t r i / is the calculation of reactants and products in chemical reactions. Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products, leading to the insight that the relations among quantities of reactants and products typically form a ratio of positive integers.
