WebAug 17, 2024 · The weighted average is determined by multiplying the percent of natural abundance by the actual mass of the isotope. This is repeated until there is a term for each isotope. For chlorine, there are only two naturally occurring isotopes so there are only two terms. Supplemental Resources WebIn general the equation for an element with [n] isotopes is: n ∑ i = 1Ximi = mave Note, the equation for two isotopes has 5 unknowns, and you can get m ave from the periodic table, so you need to be given three of the other variables to solve the equation (one equation can only be solved for one unknown).
