Finding abundance of isotopes

WebThe formula to get a weighted average is the sum of the product of the abundances and the isotope mass: A = ∑ i = 1 n p i A i For carbon this is: 0.989 × 12.000 + 0.0111 × 13.003 = 12.011 As you can see, we can set the abundance of one isotope to x, and the other to 1 − x. If x = 0.989, then 1 − x = 0.0111, OR if x = 0.0111, then 1 − x = 0.989 . http://teiteachers.org/average-abundance-periodic-table

WebThis table lists the mass and percent natural abundance for the stable nuclides. The mass of the longest lived isotope is given for elements without a stable nuclide. Nuclides marked with an asterisk (*) in the abundance column indicate that it is not present in nature or that a meaningful natural abundance cannot be given. The isotopic mass WebOne isotope makes up ~99% of all carbon, the other makes up ~1%. Clearly the isotope that makes up 99% needs to be given more importance. There is more than one way to take an average. What you generally think of when you hear average is called the arithmetic mean, this average is called the weighted mean. ( 16 votes) Show more...
