It depends on the density of the object that weighs one pound, and how much of it is under water. The object will weight 1lb - water density * object volume under water; If the object is on average is less dense the water (i.e. is buoyant), and is allowed to swim, its weight will be 0 because proportion of its volume under water will compensate gravity exactly.
it depends on the size
880 ml of PURE WATER weighs 1.94 pounds. Some liquids would weigh a bit less than that (gasoline for example) while others would weigh a bit more (salt water for example).
Well that depends on what you made the bottle out of and how much of that material you used. But the water inside would weigh approximately 473 grams (roughly 1 pound) depending on certain environmental conditions
because the upthrust force of the water acting on the stone was pushing the stone upwards meaning it was acting against the downwards weight of the stone (its weight). This meant that the downwards force was decreased and therefore felt lighter :)
This would be 1200 pounds more or less. Pounds is a unit of mass/weight. Gallons is a liquid measure. They do not convert cleanly. The density of the liquid being measured can make a big difference. If the liquid is water, there is 8 pounds to a gallon.
Objects under water seem to weigh less but they have the same mass as they would out of water.
you would weigh 200 lbs. in water as you would on land. Your body just moved the water out of the way, which explains displacement. Buoyancy is what makes you seem lighter though. Because you weigh more than the water that you displaced and because the the water that you moved has a weight too, your body would be forced up after moving the water out of the way. So it's not that you weigh less in the water if someone picks you up, they just have more help when lifting you.
They would weigh 213 pounds on Jupiter.
One cubic centimeter of water would fit into that cup, and it would weigh 1 gram.
50 oz of water would weigh approximately 3.13 pounds.
No.
I litre of water weighs one kilogram on year and would weigh 0.1 kilograms.
they would weigh the same everywhere
To calculate someone's weight on Mars, you would multiply their weight on Earth by Mars' gravity (0.38). So, if someone weighs 150 pounds on Earth, they would weigh about 57 pounds on Mars.
200 gallons of water would weigh approximately 1,667 pounds.
If someone weighs 100 lbs on Earth, they would weigh about 89 lbs on Uranus. This is because Uranus has a smaller gravitational pull compared to Earth.
100 liters of water would weigh approximately 100 kilograms, as the density of water is 1 kg/liter.
