They will eat some of it, as SilverFox says. They will burn it up rearing brood, but it's good to have some young bees going into winter. They will store some of it and dry it down to 18% moisture or so (2:1 is about 25%). There really is no way to predict how much they will spend on brood, eat, or store. They will burn up a frame of honey and a frame of pollen and an equal amount of water raising one frame of brood.
