WebDec 24, 2024 · The chlorine isotope with 18 neutrons has an abundance of 0.7577 and a mass number of 35 amu. To calculate the average atomic mass, multiply the fraction by the mass number for each isotope, then add them together. Average atomic mass of chlorine = (0.7577 ⋅⋅ 35 amu) + (0.2423 ⋅⋅ 37 amu) = 35.48 amu. Another example is to …
WebFeb 17, 2024 · The weighted average atomic mass would be: Weighted average atomic mass = (100 amu x 0.9) + (110 amu x 0.1) = 90 amu + 11 amu = 101 amu. So the atomic mass of this element would be approximately 101 amu. Note: The abundances should be expressed as fractions, not as percentages. WebJun 2, 2024 · It's easy to find the mass of a single atom using Avogadro's number. Simply divide the relative atomic mass of the element by Avogadro's number to get the answer in grams. The same process works for finding the mass of one molecule. In this case, add up all the atomic masses in the chemical formula and divide by Avogadro's number.
