What is the average … WebAr-40 is 99.6% of Ar and it weighs 39.96 amu and so on. So the atomic mass of Ar is 0.99639.96 + 0.0006337.96 + 0.00337*35.97 = 39.957. I divided the percentages by 100 to get fractions and then each mass contributes to the atomic mass according to its fraction -- weighted average.
WebA naturally occurring sample of chlorine is 75.78% chlorine-35 and 24.22% chlorine-37, so, to calculate the average mass, we need to do the sum. 35 ×0.7578 +37 ×0.2422 = 35.5. which gives us the mass shown on the periodic table, 35.5 u. Here is a video which summarizes how to calculate average atomic mass. video from: Noel Pauller.
WebThe average atomic mass (sometimes called atomic weight) of an element is the weighted average mass of the atoms in a naturally occurring sample of the element. Average masses are generally expressed in unified atomic mass units (u), where 1 u is equal to exactly one-twelfth the mass of a neutral atom of carbon-12.
