Calculate the atomic mass of silicon
WebThe atomic mass of an element is the weighted average of the atomic masses of the naturally occurring isotopes of that element. The average atomic masses are the values we see on the periodic table. 0.7577 ( 34.969 )+ 0.2423 ( 36.966 )= 35.453 The weighted average is determined by multiplying the percent of natural abundance by the actual … WebJun 26, 2024 · The atomic weight is calculated by adding the mass of each isotope multiplied by its fractional abundance. For example, for an element with 2 isotopes: atomic weight = mass a x fract a + mass b x fract b If there were three isotopes, you would add a 'c' entry. If there were four isotopes, you'd add a 'd', etc. Atomic Weight Calculation …
