Submarine weights can vary significantly depending on their type and size. A typical military submarine can weigh anywhere from 1,500 tons for smaller, smaller-class submarines to over 18,000 tons for larger, nuclear-powered submarines. For example, the U.S. Navy's Virginia-class submarines weigh approximately 7,800 tons, while the Ohio-class ballistic missile submarines can weigh around 18,750 tons when submerged.
The weight of an average submarine can vary significantly depending on its type and purpose. A typical military submarine can weigh anywhere from 1,500 tons for smaller, diesel-electric submarines to over 18,000 tons for larger nuclear-powered submarines. For example, the U.S. Navy's Virginia-class submarines weigh around 7,800 tons. In contrast, smaller research or tourist submarines can weigh as little as a few tons.
To determine how many submarines weigh the same as a mole of rice, we first need to know the weight of a mole of rice. A mole of rice is approximately 18 grams (considering rice's average molar mass). In comparison, a typical submarine weighs around 2,000 tons (or about 1,814,369 kilograms). Therefore, it would take an impractically large number of submarines, roughly 1,000,000 submarines, to equal the weight of a mole of rice.
Submarines stay afloat by using a combination of buoyancy and ballast control. When they want to surface, they use compressed air to force water out of ballast tanks, making the submarine lighter and allowing it to float. To dive, submarines take in water into these tanks, increasing their weight and causing them to sink. By adjusting the amount of water in the ballast tanks, submarines can maintain their desired depth in the water.
Modern submarines are designed to go much faster submerged. This design also limits their surface speed capability. WW1 and WW2 submarines were not considered true submersibles by today's standards. They were essentially surface vessels that had the capability of limited submerged operations. As such, their design and propulsion made them faster on the surface and much slower underwater. Modern submarines are true submersibles in that their only limitation is that of their crews.

Modern nuclear submarines make their own oxygen as needed by electrolyzing sea water. The amount of oxygen carried by conventional submarines depends on the design and size of the particular submarine.
