    The reaction will be: FeBr2 + K - - > KBr + Fe

    Balancing gives: FeBr2 + 2K - - > 2KBr + Fe

    The molar mass of FeBr2 is 55.85 + 2*79.9 = 215.65 g/mol.

    We divide 40 g / 215.65 g/mol = 0.185 mol FeBr2

    Based on stoichiometry:

    (0.185 mol FeBr2) (2 mol KBr/1 mol FeBr2) = 0.370 mol KBr
