1 lbs <- Stupid answer, good answer -> the average us military submarine weighs about 6,900 tons dry, but some others such as missile submarines can weigh up to 17,000 tons.
The weight of dry concrete mix can vary depending on its composition, but a typical bag of dry concrete mix weighs about 50 pounds (approximately 22.7 kilograms). This weight can fluctuate based on the specific formulation and any additives included. Additionally, when mixed with water, the final weight will increase significantly due to the water content.
Massive ballast tanks can be filled with water or air, changing the weight and buoyancy of a sub. Once dived a sub can use hydroplanes to angle it towards the surface and use propulsion to drive to the surface.

The submarine
Bangladesh has joined the consortium of SEA-ME-WE-4 submarine cable, which starts its commercial activities from 21st may, 2006.
The submarine will float when its weight is equal to the upthrust acting on it. This is because the upthrust force pushing the submarine upwards is equal to the weight of the water displaced by the submarine, resulting in a state of equilibrium where the submarine neither sinks nor floats.
Yes, the buoyant force acting on a submerged submarine depends on the volume of water displaced by the submarine, not directly on its weight. According to Archimedes' principle, the buoyant force is equal to the weight of the water displaced, which is determined by the submarine's submerged volume. However, for the submarine to be neutrally buoyant and maintain a certain depth, its weight must equal the buoyant force.
A submarine actually controls its weight by allowing water to enter or exit hollow chambers in its hull. These chambers are called ballast tanks. Ballast is anything carried in a ship to give stability. When water is allowed to flood into a submarine's ballast tanks, the weight of the submarine increases. When this increased weight exceeds the submarine's buoyancy, the submarine will sink. To allow the submarine to rise, air is pumped into the ballast tanks. The air forces out the water, reducing the weight of the submarine. The submarine then becomes lighter, buoyancy increases, and it floats to the surface. A submarine can also be made to "float" underwater at any depth by adjusting the amount of water weight in its ballast tanks.
The buoyancy force on a submerged submarine equals the weight of the water displaced by the submarine. This force acts in the opposite direction to the gravitational force, allowing the submarine to float or sink in the water.
I dont really get the question but a submarine?
The cast of Capture totale - 2005 includes: Sharon Stone as herself
the weight of the ocean water displaced by the submarine.
25,000 tonnes
Submarines can pump sea water into or out of ballast tanks, if they wish to change their weight (of course, anything that enters or leaves a submarine will also change its weight - people, supplies, weapons, etc. - but if you just want to change the weight, the easiest way is to pump water into the submarine).
Totale's Turns - It's Now or Never - was created on 1979-10-27.
To rise again, the submarine's weight must be decreased. Air is pumped into the ballast tanks to force the water out. The buoyant force acting on the submarine now exceeds the submarine's weight. With positive buoyancy, the submarine rises. The less weight an object has the more its density decreases. Hope that kinda helps?
This is not a "cut and dry" question. It depends on the pay grade and whether they are wearing their "dophins" or not. They cannot receive submarine pay until they finish the submarine qualifications and put on the submarine pin or "dolphins".
