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.

Phet isotopes and atomic mass answer key - AnswerData

WebFind the average atomic mass of an element given the abundance and mass of its isotopes. Predict how the mass and name of an isotope will change given a change in the number … Webaverage mass = ∑ i ( fractional abundance × isotopic mass) i. For example, the element boron is composed of two isotopes: 19.9% of all boron atoms are 10 B with a mass of 10.0129 amu, and the remaining 80.1% are 11 B with a mass of 11.0093 amu. The average atomic mass for boron is calculated to be: boron average mass. WebUse the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.
