Input: Density is defined as mass per unit volume; mathematically, we would write: or mass m density d Volume V = = For any pure substance or homogenous mixture, density is an intensive quantity, which means that its value is the same no matter how much of the substance is present. Density expresses the proportional relationship between mass and volume of the substance. If the density of a particular substance is given in grams per milliliter, it indicates the number of grams present in 1 milliliter of that substance. To calculate the density (usually represented by the Greek letter ) of an object, take the mass (m) and divide by the volume (v): = m / v. The SI unit of density is kilogram per cubic meter (kg/m3). It is also frequently represented in the cgs unit of grams per cubic centimeter (g/cm3). A concept related to density is the specific gravity (or, even more appropriate, relative density) of a material, which is the ratio of the material's density to the density of water. An object with a specific gravity less than 1 will float in water, while a specific gravity greater than 1 means it will sink. As a result, temperature and pressure can greatly affect the volume of a substance, especially gases. As with mass, increasing and decreasing the amount of material also increases and decreases the volume of the substance. Density. Density is calculated by dividing the mass by the volume (density = mass/volume). For example, 10 grams of freshwater has a volume of 10 milliliters. This results in a density of one gram per milliliter (10 g 10 mL = 1 g/mL). Unlike mass and volume, increasing the amount of material measured does not increase or decrease density. density, of a substance is its mass per unit volume. The symbol most often used for density is (the lower case Greek letterrho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: where is the density, m is the mass, and V is the volume. The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume:[1] Density is a measure of mass per unit of volume. Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water). Perhaps the highest density known is reached in neutron star matter. #Density# = #Mass/Volume# To solve the equation for Mass, rearrange the equation by multiplying both sides times Volume in order to isolate Mass, then plug in your known values (Density and Volume). Then solve for Mass. #Mass# = #Density x Volume# Example. The density of copper is #8.933 g/cm^3#. Density equals mass divided by volume: d = m/v So the density will vary depending on how the mass and the volume vary. If you know two of the values, you can plug them into the equation and use algebra to solve for the missing value. Specific gravity is a comparison of the density of a given material to the density of water. Water has a density of 1 gram per cubic centimeter (at 4 degrees C). That makes the math really easy. 1.93 g/cc compared to 1 g/cc equals a specific gravity of 1.93 for the clay in the brick. Note that specific gravity has no units associated with it. It's a number only. We've used mass and volume to find density, and then compared the density of our stuff to that of water to find its specific gravity. Piece of cake. Query: how is density and volume related
Output:
Density is a measure of mass per unit of volume.
