Answer:

There are #3.08*mol# #"bromine atoms........"#, i.e. #3.08*molxx6.022xx10^23*mol^-1# individual bromine atoms.

Explanation:

You simply have to know that the bromine molecule is binuclear under standard conditions, i.e. #Br_2#, and the rest of halogens are also #X_2#.

And so we gots #1.54*mol# with respect to molecular #Br_2#, i.e. #3.08*mol# bromine atoms. Are you with me?
