# what is density in chemistry

An alloy has a density of #rho=8.900xx10^3*kg*m^-3#...can you address the following question? Less dense materials have a smaller concentration of mass in a given volume, or a mass spread out over a large volume of space. Since density is a ratio of mass to volume, it remains constant for a substance. Stoichiometry • It becomes liquid as a result of parting molecules. A cube measures 2.0 cm on each edge and has a mass of 64.7 g. Calculate the density of the material that composes the cube. When the rock is submerged, the water level rises to 56.8 mL. You’ve got a very low quantity of disorder. Mathematically, density is defined as mass divided by volume: = where ρ is the density, m is the mass, and V is the volume.

What mass of solute is present in #24*mL# of #0.10*mol*l^-1# aqueous sodium chloride solution? Periodic Table • Airplanes may sink in water but float in air. What is its density? What is its density in #"g/cm"^3"#? Increasing the temperature increases the sum of vapor that’s formed and therefore the vapor pressure.

Thus, let’s say you experience an object composed of an unknown substance. Conceptually, density is best described as the compactness of a material. Usually the density is expressed in grams per mL or cc. Water is used as the common standard to substances, and it has a density of 1000 kg/m3 at Standard Temperature and Pressure (called STP). Density indicates how much of a substance occupies a specific volume at a defined temperature and pressure.
