There is no standard answer because the density of the pellets vary too much. Take a quart of your feed and weigh it on a kitchen scale to get an accurate weight.
how much does a gallon of concrete weigh
There is no one standard weight for pelleted horse feed. This is due to the size of the pellets, how moist they are and what is in them. Horses should be fed by weight and not by the scoop so it is best to weigh out one whole scoop on a scale to see how much your pelleted feed weighs.
It would depend on what type of grain. But it would probably be somewhere in the range of 7 to 10 lbs.
1 gallon
