WebJan 23, 2024 · Atoms of both isotopes of carbon contain 6 protons. Atoms of carbon-12 have 6 neutrons, while atoms of carbon-14 contain 8 neutrons. A neutral atom would have … WebThe 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. The half-life of carbon-14 is approximately 5,730 years, and it can be reliably used to measure dates up to ... Web1 egg mass = 60g and 1 dozen = 12. Therefore, 1 dozen of egg masses = 1 dozen of 60g = 12 of 60g = 12 x 60g = 720g Example 2: Show that 1 mole of 12C is 12g. Recall that, 1 amu = 1.6605 x 10^ (-27) kg and 1 mole = 6.02 x 10^23. 12C = 12 amu Therefore, 1 mole of 12C = 1 mole of 12 amu = 1 mole of 12 x 1.6605 x 10^ (-27) kg fixed cone roof
