Gallons, as a form of measurement, is typically only applied to liquids and not to gases. A gallon is, however, a measure of volume. And assuming that you were talking about 1 gallon of distilled pure water being heated from zero degree Celsius until it is completely converted to steam, the answer is 8.33 lbs - the same as it weighed as a liquid. The solid, liquid and gas form of this much water will weigh 8.33 lbs. This assumes that none of the mass gets converted to energy, which it shouldn't, and also that it is weighed here in the laboratory and not on the moon or at some other location.
The weight of water is approximately 8.34 pounds per gallon. So, 400 gallons of water would weigh around 3,336 pounds.
375 US gallons of water is about 3,131.25 pounds.
A 100-gallon fish tank weighs approximately 834 pounds when filled with water. The weight of the tank itself can vary depending on the material it is made of, but the water alone would weigh around 8.35 pounds per gallon.
Seawater weighs about 27 grams per litre more than fresh water.
A gallon of water weighs about 8.34 pounds. So, a 50 gallon water heater full of water would weigh approximately 417 pounds.
Weigh an empty container; pour a gallon of water into it. Weigh it again. Calculate the difference. That is the weight of the gallon of water.
One gallon of distilled water weighs approximately 8.34 pounds at room temperature.
== Probably close to the weight of water. 8.34 lbs per gallon.
The weight of water is approximately 8.34 pounds per gallon. So, 400 gallons of water would weigh around 3,336 pounds.
The weight of a measurement of volume is determined by the mass and weight of the substance whose volume is measured. A gallon may weigh a few ounces, or a gallon may weigh several hundred pounds.
Weight of 1 US Gallon of water = approx. 8.35 lb
A little less than one gallon of water which is (depending on the temp of the water) 8.34 lbs.
The weight per US gallon of water at 25 C is 8.33 pounds [per gallon. 2 gallons of water would weigh 16.66 pounds plus the weight of the bucket itself.
A gallon of water weighs about 8.34 pounds. If you have a good sized bucket with a gallon of water in it and you put a 5-pound fish in the bucket, you'll have a bucket that weighs about 13.34 pounds (plus the weight of the bucket). That's as long as the bucket doesn't overflow. The fish will (usually) be neutrally bouyant in the water, and it will be essentially weightless in that water. But its weight will add to that of the water in the bucket. No, it won't weigh 15 pounds, but it will weigh in as suggested. However, the weight of the water itself will not change.
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:)
Weight of 1 US Gallon of water = approx. 8.35 lb (about 3.785 kg) Weight of 1 Imperial gallon (i.e. UK measure) of water weighs 10 pounds (4.536 kg) by definition, at a specified temperature and pressure.
If you take the molecular weight of water is it around 18 g/ mol. The simplest glucose molecule weighs around 180 g/mol. So the right answer to the question would be NO.
