We are asked to determine the average molecular mass of a Br2 molecule.
Mass spectroscopy is an analytical technique that plots ion signal (fractional abundance) as a function of mass-to-charge ratio.
We will solve for each atom’s average mass using their relative size (fractional abundance).
The formula for average mass is:
|Mass (amu)||Relative Size|
Determine the average molecular mass of a Br2 molecule.
