Air at sea level weighs about 1.2 kg per cubic meter. You can find that using the ideal gas law pV=mRT where p is pressure V is volume m is mass of gas R is the gas constant for air = universal gas constant/average molecular mass of air T is the temperature in absolute units. All of those are better in metric units, so p is in pascals, V is in cubic meters, m is in kilograms, T is in kelvins, and R is 8314/28.8 = 288 N-m/kg-K. At sea level, standard pressure is 101325 Pa, temperature is about 20 deg C or 293 K. For a volume of 1 cubic meter, m/V = p/RT = 101325 / (288 * 293) = 1.201 kilograms per cubic meter. Since you wanted to know gallons, 264.2 gallons is 1 cubic meter, and 2.204 lb in one kg, so 1.201 kg/m^3 * (1 m^3/264.2 gal) * (2.204 lb/kg) = 0.0100 lb/gal. Not a heckuva lot, but not zero. One thing to notice is that if you put a gallon of air on a scale, (in a wieghtless container, of course) you would measure zero, exactly. That's because the buoyancy caused by the surrounding air exactly counteracts the weight of the air in the container. If you pressurized the air in your gallon container to, say ten times the outside pressure (or 147.0 psi absolute, or 132.3 psi gauge) it would now weigh nine times 0.01, or 0.09 lb. Of course, the container that held all that pressure would have to weigh a lot more than 0.09 lb, so measuring the change would require a very good scale.
The weight of 6% KCl (potassium chloride) solution is 6 pounds per gallon. This means that in one gallon of the solution, 6% of the weight is potassium chloride, which amounts to 6 pounds.
== Probably close to the weight of water. 8.34 lbs per gallon.
One gallon of sodium bisulfate weighs approximately 10.7 pounds.
phosphorus' atomic mass,it's weight,is 30.974 the atomic number on the other hand is 15
The weight of one gallon of chlorine bleach is 8.375 pounds!
The weight of one gallon of isopropanol is approximately 6.59 pounds.
It is roughly the same as the weight of a gallon of water, because the bouyancy force is equal to the weight of water displaced (the weight of the air being negligible). A UK gallon of water weighs almost exactly 10 pounds, while a US gallon weighs about 8.35 pounds.
not just one gallon
The weight of 1 gallon of gasoline equals 5.8 to 6.5 lbs.
"It should weight 8lbs, because you have 128 oz to one gallon and it takes 16 oz to make one pound. Not sure what the gallon itself weighs." NO! Liquid ounces do not equal weight ounces! I gallon of coconut oil is approximately 9 pounds.
One gallon of pure water weighs 8.345 pounds.
A gallon of water weighs 8 pounds.
One gallon of F-24 weighs approximately 6.36 pounds.
One US gallon of gasoline is approximately 6.3 pounds
Good question but I can tell you that the weight of the oil has no bearing on the weight of the gallon. Look for a conversion chart and see what a gallon weighs of any liquid. Can be found in the front of your phone book or in a book at your local library or in a diet book. It is sold in 120lb. packages and there are 16 gallons per package. Therefore one gallon weighs 7.5 lbs. I believe 30-weight oil is 6.8 lbs/gal. One gallon of feathers does not weight the same as one gallon of water.......
The buoyant force is equal to the weight of the displaced fluid (Archimedes Principle). A gallon jug underwater will have a buoyant force equal to the weight of the displaced water: eight pounds. The total weight will also include the normal downward weight of the jug itself and the air it contains.
The weight of a gallon of water is about 8.34 pounds at 17 degrees Celsius. At different temperatures, the weight will be different. This is in Imperial measurements, where an Imperial gallon is equal to 4.54609 liters.
