Kosher salt grains are larger than table salt and are of irregular shape.
I'd guess there is more air between the grains. That's "void" I guess. The
Kosher grain may be less dense than the table salt grain.

I just weighed Morton's table salt and came up with 1.3 ounce by weight to 1
ounce by volume, for a specific gravity of 1.3. One ounce by volume of table
salt is therefore 4.06% by weight per 32 oz quart of water and 8.13% for two
ounces of salt per quart.

Thanks for your post. I've seen the figure 2.15 attached to the words "table
salt". I can't find the 1.028 figure, though I'm sure you're right on.
