how much does a filled 40 gallon water heater weigh?

The same as an empty one. You can maybe find the shipping weight on the side. about 100 lbs?\nOh and that's not counting the forty gallons of water 333.81616 lbs. But that's the water, not the heater\nJeronimo!

should weigh around 9 oz, got this at parenting.com. enjoy

The circumference is 68–70 cm (or 27–28 inches), with a weight of 410–450 g (or 14–16 ounces), inflated to a pressure of 60–110 kPa (or 8.5–15.6 psi).

16 oz in a pound, 32 oz in a quart, 2 pounds in a quart, same with metric

There is no equation to convert mass into weight, because it all depends on the density of the material. Even something as simple as a liter of water won't always weigh the same each time, because the temperature will change its density. Hot water is less dense than cold water, therefore the same volume of hot and cold waters don't weigh the same. Another example. Take a gallon of flour and weigh it. Now fill that same gallon container with sand and weigh it. It will not weigh the same because sand is denser than flour. \nThe bottom line is, you can't convert mass into weight because there are too many variables for one equation to solve all problems.

Well first lets get the weights figured out,\n\n9% soloution,\n\nweight= (9.57 lbs/ gallon) * 6 gallons\n      = 57.42 lbs\n\n0.5% soloution,\n\nweight = (8.34 lbs/gallon) * 60 gallons\n       =500.4 lbs\n\nTotal weight = 500.4 lbs + 57.42 lbs\n             = 557.42 lbs\n\n\nnow 9% of 57.42 lbs= 5.1678 lbs\n    0.5% of 500.4 lbs= 2.502 lbs\n           Total = 2.502 +5.1678\n                 = 7.6698 lbs\n\nso to get the percentage,\n\n7.6698 lbs / 557.42 lbs\n=0.01376\n=1.376% (approximatley)\n\nSo the conecntration is approx 1.4%\n\nhope that helps

At room temperature, the density of mercury is 13.54562 greater than the density of water, and decreases slightly as the mercury is heated.\n\nA gallon of water wieghs exactly 8 pounds, so a gallon of mercury at room temperature would weigh 13.54562 times as much.

when u buy gas for ur cooker it is filled in the gas cylinder and it is weighed,i think if u want the real weight try weighing the container before weighing it with the gas, subtract the initial weight from the final and u will get it

The density is 0.357 g/mL. This is because specific gravity is the ratio of the density of the unknown liquid to the density of water, 1.0 g/mL.\n\nIf, say, you wanted to know the density of the liquid in pounds per gallon, you would multiply 0.357 by the density of water, which is 8.320 lb/gal

Given:\nm <mass of substance> = 12.0g or 12/1000 kg\nc <specific heat capacity of water> = 4180J per kg per degree celsius\nt <change in temperature> = 20 degrees to 100 degrees i.e. 80 degree celsius\n\nFind:\nHeat req.\n\nSolution:\nHeat required or Q\nQ = m * c * t\n  = 12/1000 * 4180 * 80\n  = 12/10 * 418 * 8 (cancelling 0s of 4180&80)\n  = 12/5 * 209 * 8 (div. 418&10 by 2)\n  = 12/5 * 1672 (mult. 207&8)\n  = 20064/5 (mult. 12&1672)\n  = 4012.8\n\nAnswer = 4012.8 Joules or 4.0128 KJ

Sorry, but this is not chemistry. This is just math.\n\n$2.99/50.2 g x 454g/lb = $27.04/lb

Easy.  \n\nYou have q = mass * specific heat * change in temp.\n\nFind the specific heat of water and your set.  Q is joules so you need to convert.

The density of diesel fuel varies from one refined lot to the next. The density of diesel fuel ranges from 82%-95% that of water.\n\nSince the weight of water is 8 lbs/gallon, it would stand to reason that a gallon of diesel fuel would be between 6.5 lbs and 7.6 lbs.

Water at sea level weighs about 8.3 pounds per gallon.

Water weighs 8.34 pounds per gallon\n\n1 cubic feet of volume holds 7.5 gallons of water\n\nfind the cubic feet volume of the tank (LxWxH) which is 30 \n\nthen multipy the cubic feet by the 7.5 which is 225 pounds.  Pretty heavy huh:)

It is filled with air.  It has a circumference of 27-28 inches with a weight of 14-16 ounces.  It should have the air pressure of 8.5 to 15.6 PSI.
