Table of Isotopic Masses and Natural Abundances

WebAn imaginary atom has only 2 isotopes and an average atomic mass of 74.90 u. If Isotope 1 has a mass of 73.95 u and Isotope 2 has a mass of 75.92 u, calculate the natural abundance of Isotope 1, in percentage. Note: u is the symbol for an atomic mass unit, sometimes written as amu. Enter the numerical value only below (without the % symbol ... WebThe table below shows the exact mass of each isotope (isotopic mass) and the percent abundance (sometimes called fractional abundance) for the primary isotopes of Carbon. Average Atomic Mass = (12.0000) (.9890) + (13.0033) (0.0110) = 12.011 amu. The answer, 12.011 amu, is the same value found for Carbon on the periodic table. t on the green tottenham https://sluta.net
