Why is the mass in amu of a carbon-12? – AnswersAll
Web24 apr. 2024 · The mass of a carbon-12 atom is exactly 12 amu. The atomic mass of carbon is listed as 12.01 amu in the periodic table because most naturally occurring … Webexplain many experimental observations in Organic Chemistry, however, ... (amu) is defined as exactly 1/12 of the mass of 12C, the atomic mass of 12C is 12.0000 amu; the atomic mass of 13C is 13.0034 amu. Therefore, the atomic weight of carbon is 12.011 amu because (0.9889 * 12.0000) + (0.0111 * 13.0034) = 12.011. impact sensor for cars
