calculate density of sponge ?
It depends of the piece of wood itself and the type of wood that it is.
The density of this piece of wood would be 456.7 g/cm^3.
The volume of the piece of wood is (10 x 5 x 3) = 150 cubic cm. In order to find its density, you also have to know its mass. When you have that, divide it by 150 cm3, and the answer is the density.
The density of a piece of granite with a volume of 340 cm and mass of 918 g would be 1,400 grams. This is a math problem.

Sodium (Na) and Chlorine (CL) combine to form Sodium Chloride- (NaCl)- but you probably call it table salt.
Copper has a giant structure, in the sense that all its electrons can move freely through the entire mass of a single piece of the element. Chlorine has distinct molecules, and glass and sodium chloride are not elements but compounds.
Where is the density of a Chess piece
Pure sodium is reactive, in a rather violent way. Any free sodium that could exist naturally would have reacted so as soon as it came into existence. It is unstable, and can only be stable as a compound with other elements like chlorine (sodium chloride).
No.Take common table salt. Sodium Chloride. If you put a piece of sodium metal in your mouth and inhaled some Chlorine gas you would die.
The density of sodium is 0.968g/cm3 which is just slightly lower than that of water, which is 1.00g/cm3. When sodium is added to water, the piece of sodium would float and sometimes dart around the sides of the beaker. It is a violent reaction and the heat evolved from the exothermic reaction is sufficient to ignite the hydrogen gas and cause the sodium to burn.
-- Get a pure piece of it. The size of the piece doesn't matter. -- Measure the mass of the piece. -- Measure the volume of the piece. -- The density of the substance is mass of the piece/volume of the piece.
44.16g density times volume
The wood is "lighter" (weighs less; has less mass) than the iron because of it's density. Iron has a greater density than wood, and density is defined as mass/volume, so having the same volume (size), the iron will have a greater mass.
