Can't be answered unless you know how much air is between the chunks. The density of NaCl is 2.16 g/cm3. A cm3 is the same as a milliliter.
There are 3785.41178 ml in a gallon so a gallon would weigh 3785.41178 x 2.16 grams = 8176.4894448 grams.
So, in pounds, a chunk of NaCl (with no air space) would weigh 18.0260736 pounds...and, since the least precise term (presuming that "a gallon" is infinitely precise) was the density, that answer ought to be rounded to 3 significant digits: 18.0 pounds.
