abundance of isotopes

p4cifico

Element x has two naturally occurring isotopes. The masses (amu) and % abundance are given. 31x is 35% with mass of 31.16 and 34x is 64% with 34.3 amu's

i suppose you have to calculate the atomic mass of the element??!! huh

let's take the example of chlorine, which has two istopes too. Cl-35 and Cl-37, in the ratio of 3:1.

on average, chlorine atoms have atomic mass of: [(35 * 3) + (37 * 1)] / 4

similarly, you can calculate the atomic mass of x, if that's what you were asking??!!

Are you familiar with the term 'weighted average'?
