The Formula for convert API gravity to pounds per gallon is: Pounds per Gallon = (141.5/(API Gavity+131.5))*8.3378 <--[which is weight of fresh water] API of 10 is same as weight of water. API >10 will float
I gallon (Imperial) weighs just over 10 pounds-weight.
The average ocean or sea has a salinity of about 3.5%. In metric, about 35 grams per liter.
100 proof alcohol is 50% alcohol and 50% distilled H20. The weight of alcohol is 7 lbs per gallon and the weight of distilled water is 8.34 pounds per gallon. if you mix them 50/50 you should have a final weight of 4.17 + 3.5 = 7.67 pounds:)
Iridium is the densest material known.
liquid mercury's weight is 30 times the weight of water. Water's weight is 8 lbs per gallon, 30 times the weight of water will be 240lbs for a gallon of liquid mercury.
Salt water is at it's lowest freezing point at a 23.3% salt-to-water solution. This works out to 2.28 lbs. of salt per gallon of water. Source: http://www.varitech-industries.com/pdfs/Salt%20Brine%20Statistics%20and%20Rock%20Salt.pdf

Assuming that "wiegt of wateer" is meant to be "weight of water", the answer is 133.44 oz per gallon.
Most chlorine generators require a salt content in the water of a pool 2500 to 6000 ppm
The mass and weight of a gallon of sea water depend upon the temperature and salt concentration in the sea water. Assume T = 60.0 F and C sub salt = 4.0 mass percent d = ( 64.0 lbm / ft^3 ) ( 1.0 ft^3 / 7.4805 gal ) = 8.56 lbm / gal m = ( d ) ( V ) m = ( 8.56 lbm / gal ) ( 1.0 gal ) = 8.56 lbm <-----
The weight per a us gallon of diesel is about 7.49 lb.
Weight of 25% sulfuric acid per gallon
Density = 8.345 lb/gallon (this is an odd density, because density changes depending on temperature, and this number is actually for 40°F water, but that's not relevant to this question)Density (d) = Mass (m) / Volume (V)d = m/Vm = Vdm = (1 gallon ) ( 8.345 lbs / gallon ) = 8.345 lbsThe water (without the salt) weighs 8.345 lbsIf you add 3 lbs of salt, you are just adding 3 lbs of salt. Just add 3 to the weight. This part is just to trip you up.8.345 + 3 = 11.345 lbsThe water with the salt weighs 11.345 lbs.
How much salt should be added to hard water depends on what you want to accomplish by adding the salt.
The average weight of one gallon of #2 fuel oil is 7.2 pounds. Water weighs 8.34#/gal.
