how much does a gallon of mercury weight?
444934
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.

The mean surface temperature of Mercury is 452 K (178.8 °C /353.9 °F), but it ranges from 90 K (-183.15 °C /-297.7 °F) to 700 K (426.85 °C /800 °F); by comparison, the temperature on Earth varies by only about 150 K (150 °C /270 °F). The sunlight on Mercury's surface is 6.5 times as intense as it is on Earth, with the solar constant having a value of 9.13 kW/m².

I think you must mean, "How many liters are there in a gallon?" There are 3.785 liters in a gallon.

According to Google:\n1 ounce = 28.3495231 grams\n\nYou can double check this if you know that there are about 454 grams in a pound.  454/16 ≈ 28+ grams

it seems that no one has answered this question.\n\nfirst, i will give mercury's mass for comparison:\n\n3.302 x 10e+23 kg\n\nthis is your answer\n\nganymede . . . . . . . . . .1.482 x 10e+23 kg\ntitan . . . . . . . . . . . . . . . .1.345 x 10e+23 kg\ncallisto . . . . . . . . . . . . . 1.075 x 10e+23 kg\nio . . . . . . . . . . . . . . . . . . 8.932 x 10e+22 kg\nmoon . . . . . . . . . . . . . . .7.348 x 10e+22 kg\neuropa . . . . . . . . . . . . . . 4. 80 x 10e+22 kg\ntriton  . . . . . . . . . . . . . . . .2.147 x 10e+22 kg\ntitania . . . . . . . . . . . . . . .3.526 x 10e+21 kg\noberon . . . . . . . . . . . . . .3.014 x 10e+21 kg\nrhea . . . . . . . . . . . . . . . . 2.317 x 10e+21 kg\n\ni would like to add that triton was not a satellite of neptune originally, but neptune captured it.  that is why triton has a "retro" (retrograde) orbit.\n\nhttp://en.wikipedia.org/wiki/Mercury_%28planet%29\n\nhttp://en.wikipedia.org/wiki/Ganymede_%28moon%29\nhttp://en.wikipedia.org/wiki/Titan_%28moon%29\nhttp://en.wikipedia.org/wiki/Callisto_%28moon%29\nhttp://en.wikipedia.org/wiki/Io_%28moon%29\nhttp://en.wikipedia.org/wiki/Moon\nhttp://en.wikipedia.org/wiki/Europa_%28moon%29\nhttp://en.wikipedia.org/wiki/Triton_%28moon%29\nhttp://en.wikipedia.org/wiki/Titania_%28moon%29\nhttp://en.wikipedia.org/wiki/Oberon_%28moon%29\nhttp://en.wikipedia.org/wiki/Rhea_%28moon%29

The density will be the same no matter how much you have. It is less than 1 because it floats in water. A gallon of gas weighs 6 pounds. A gallon of water weighs 8 pounds. So  it is around 6/8 or .75 That was just an estimate.\n\nI just checked in a reference and it says .66g/ml

1 pound = 453.6 g\n1 pound = 16 oz\n16 oz = 453.6 g\n16 / 453.6 oz = 1 g\n.03527 oz = 1 g

First you need an element. Then you need its atomic mass rounded off to the nearest whole number. \nWhen you see it written in an equation it can be read as moles or grams. When you go to use the information, you figure the mass in grams of the number of moles present in the equation.\nSay you have H2O. H weighs 1 and there are 2 of the H's.Oxygen weighs 16. The molar mass of 1 mole of  water is 18 g

Hey dummy - the US gallon is actually the older of the two measurements. Great Britain changed what was then called the "Liquid Gallon" (now known as the "US Gallon") into what is now the "Imperial Gallon" or the "Ale Gallon" in order to have an easily calculable relationship with the pound (weight, not money). Read all about it here before you make a fool of yourself again.\n http://en.wikipedia.org/wiki/Gallon\nThe United States didn't change the gallon, Great Britain changed it!!!

heh, close.  128 oz. in 1 gallon, x 50 = 6400

Technically, you really want to know which has more mass (greater gravitational effect), or which has greater density.  Earth by far has more mass, and is far larger.  On the other hand, they are very close in average density.  The average density of Earth is 5.515 g/cm^3 (the densest planet in the solar system), the average density of Mercury is 5.427 g/cm^3 (#2).\n\nThe reason for this is quite interesting.  Like Earth, Mercury has an iron rich core, which means that early in its life Mercury separated out into the heavy dense metals and lighter rocks.  The light stuff floated to the top and became the crust, and the heavy stuff sank to the middle and became the core, just like Earth.\n\nIt seems, though, that sometime early in Mercury's history is collided with a huge planetesimals.  The collision stripped away almost all the crust, sending it into the sun and to the outer planets (Venus and Earth).  It was a cataclysmic collision, destroying the planet that was Mercury and leaving barely more than the core, which is what there is now.  Mercury used to be about 2.5 times bigger than it is now, bigger than Mars and rivaling Earth and Venus.  But because of that collision, little more than the core remains, which is why it is so dense.

It is  1.008 g/mol. for hydrogen atoms\n\nOne hydrogen atom weights on the average 1.67323 * 10^-24 grams.\n\nHydrogen gas contains 2 atoms so it weights 3.4646 *10^-24 grams.\n\nAverage mass is average abundunce of all the isotopes of hydrogen
