Question

A new element, Thorsonium, has two isotopes. Thorsonium isotopes have a mass of 255 amu and 257 amu. Given the average atomic mass of Thorsonium is 255.65 amu, calculate the percent abundance for each Thorsonium isotope.

Answer 1

255 amu has relative abundance 67.5% and 257 has relative abundance 32.5%

Step-by-step explanation:

Average atomic mass =sum of product of atomic mass and relative abundance all divided by hundred or total abundance
