It's easy enough to find out. Carefully weigh out 1 pound, add water and dissolve, make up to 1 gal (at the reference temperature for your hydrometer) and measure the specific gravity. Voila!
I don't mean literally one pound in 1 gallon but 2 Oz in 1 pint or 1 Oz in a cup or whatever scaling seems reasonable.
