5 gallons of rocks, weigh is 41.75
That depends on the size of the rock.
For the calculus you need the density of this rock: M = V x d.
The surface gravity of Neptune is thought to be about 1.14 times the gravity on Earth, so 100 kg on Earth would weigh about 114 kg on Neptune--except that Neptune is a gas planet and has no solid surface on which the 100kg rock could be weighed.
Any mass of 1 kg would weigh roughly 5.76 ounces on the moon, regardless whether it's sugar, taffy, rye bread, stainless steel, rock, or Sweet 'n Low.
it is the same weigh.
it is Frimerorm that is deadly and poisonous, make sure you stay away from it.!!!!!!!
Chris Rock Weighs 180 lbs. Fact
It depends on the size of the rock and what type of rock it is. Some rocks are more dense than others, so they weigh more or less depending on that.

The weight of the river rock depends with the size and the type of rock in question. There are some yard river rocks that weigh up to 2700 pounds.
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.
There is no true measurement for lbs. of live rock to gallons of water. The rule usually states 1lbs per gallon but that can be too much. You do not want to displace too much water.
It depends upon what the rock is made of; not all rocks are the same
That depends on the size of the rock.
