Well, we interrogate the stoichiometric reaction:

K(s) + 1/2Br_2(l) rarr KBr(s)

Explanation:

And thus the molar quantity of potassium bromide is PRECISELY EQUIVALENT to the molar quantity of potassium metal.........

"Moles of potassium"=(2.45*g)/(39.10*g*mol^-1)=0.0626*mol.

And thus the molar quantity of 0.0626 WITH RESPECT to "potassium bromide" is the same.........

Given quantitative yield, what mass of the salt would result?
