Density chem definition
WebAbsorbance is defined as "the logarithm of the ratio of incident to transmitted radiant power through a sample (excluding the effects on cell walls)". Alternatively, for samples which scatter light, absorbance may be defined as "the negative logarithm of one minus absorptance, as measured on a uniform sample". The term is used in many technical … WebDensity is a measure of how tightly the mass of an object is packed into the space it takes up. It can be calculated by dividing mass by volume . \({density} = \frac{mass}{volume}\)

It is the force required to accelerate a 1-kg mass 1 m/s 2. The cgs unit of weight is the dyne.
WebThe volume is going to be 4/3 PI times 0.9 to the third power. And we know what the mass is, the mass in that volume is 8,300 kilograms. So we would know that the density, the density in this situation is going to be 8,300 kilograms, 8,300 kilograms per this many cubic meters, 4/3 PI times 0.9 to the third power cubic meters. WebDensity ( volumetric mass density or specific mass) is the substance's mass per unit of volume. The symbol most often used for density is ρ (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] where ρ is the density, m is the mass, and V is the volume.
