what is the weight of 1 cubic meter of water?

Do you mean mass or weight?\n\nTo get the mass of 1 cubic meter of water:\n\nA cubic meter is a cube 1m x 1m x 1m \n\nConvert to centimeters this gives 100cm x 100 cm x 100cm\n\nTherefore the volumen of the cube in cubic cm is 1000000 cm3\n\n1 litre = 1000 cm3 therfore :\nvolume in litres is 1000000 / 1000 = 1000 l\n\nrelative density of water is 1kg / l therefore the mass of the water is 1000kg or 1 tonne.\n\nWeight is the gravitational force exerceted on the water by the earths gravitational pull. I'm assuming the water is stationary at ground level and not in orbit or something daft. The effect of gravity at ground level is given by the constant g which is 9.8N/kg.\n\nTherefore the weight of the water is 1000 * 9.8 =  9800N

water weighs 8.345 lbs/gal.  Divide water weight lbs/gal by 8.345 and that's your answer.

One gallon of water, at 20 degrees Celsius, weighs 8.33 pounds

An object sinks when it's weight exceeds the weight of the amount of water displaced by it's volume. The density of pure fresh water is 1kg/l. Assuming the the bottle must be completely full to contain 2l of water, a 2l bottle of water will weigh 2 kg and displace 2 kg. It will have neutral buoyancy. The bottle itself will displace more than it weighs, so the bottle will float.

About 8 pounds.\n\nHere are more technical answers: \n\n\n8.34lbs \n\n1 gallon of fresh water is about 8.36 \n\nAccording to the 21st edition of The Machinery's Handbook, 1 galon of water weighs 8.337 pounds. \n\nTo answer this question more appropriately you would have to know the temperature of the water. As water cools it becomes more dense until it reaches 39.2 degrees fahrenheit. Below this temperature the density decreases and the water molecules spread apart. 1 liter of water/ice at will actually weigh less than 1 liter of water at say 80 degress fahrenheit. \n\nOne cubic foot of water contains 7.48 gallons of water, weighing in at 62.31 pounds. \n\nThe Handbook of Chemistry and Physics specifies the weight of 1 US gallon of water in air at 68 degrees F to be 8.32487 pounds or 3776.103 grams.

OK , i'll give it try.  we are assuming that the water is distilled because that affects the specific gravity.  grams per cc of h20.  4 oz. of water =1 cup......so 1oz of water =.0296 liters.......4 x that  = .1184 liters.....devide that by 1000 to get the mass or gram  value of 1.184 cubic centimeters = 1 cup of water...give me 10 pts for effort.!!  I think i messed up on the conversion but believe the answer is correct!

Looks like this is your homework. anyway, i'll only answer two of your questions.\n\n1. the density of water is almost 1 g/mL. and 1 liter = 1000 mL. hence the mass of 1 liter of water is 1000 g.\n\n2. since 1 liter of water is 1000 g or 1.00 kg, its weight is 1.00 * 9.8 = 9.80 N

ok, i'm assuming that the block is being hung into water. otherwise the problem's too easy.\nso 1.00x10^-3 m3 of water will be 1 kg, or 9.8 N. thus block weighs 19.8 N or 2.02 kg.\nThen, 2/3*1.00x10^-3 = vol of unknown liquid displaced = 6.67x10^-4 m3. since its floating, we also know that amount of liquid weighs 19.8N, or 2.02 kg, so 2.02kg/6.67x10^-4 = 3.03x10^3 kg/m3\nI hope that's right.

0.96 cubic metres of water for every metre of the canals length.\n\nor 8.24 square metres of surface covered for every metre of length.

What blaa blaaa!!!!\n\n1 cc = 0.001 L\n1 cc = 0.001 kg\nSo, 1 g  =  1 cc\n\n1 dm = 0.1 m\n1 dm = 100 mm\n1 dmc = 1,000,000 mm

The water pressure t a given depth is give as the weight of the water above that depth divided by the area it is being applied.\n\nSo imagine a column of water extending from the top of the lake down the depth.  Calculate the volume of this column of water then using the density of water (1 grams / mL) find the mass.  The take the mass of the water and find its weight (W = mg).  The weight it is the force exerted by the water, but pressure is the force of the water divided by the area it is applied.  So divide the force by the area of the base.\n\nEDIT:\nI see you added the density of water (even though I think my density [1 g/cc] is better).  I will leave you to do your own homework.\n[I also refuse to work with such an ugly unit, I prefer metric]

its all to do with weight displacement and the volume of water

volume is measured in liters or cubic meters

1 cm3 of water equals 1 gram of water.\n1 gram of water equals 0.001 kilograms of water\nThus 455 cm3 = 0.455 kg (unlike the first answer you got)
