Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [1] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase : [2]
The standard unit of specific volume is cubic meters per kilogram (m 3 /kg), but other units include ft 3 /lb, ft 3 /slug, or mL/g. [ 1 ] Specific volume for an ideal gas is related to the molar gas constant ( R ) and the gas's temperature ( T ), pressure ( P ), and molar mass ( M ):
In chemistry, the mass concentration ρ i (or γ i) is defined as the mass of a constituent m i divided by the volume of the mixture V. [1]= For a pure chemical the mass concentration equals its density (mass divided by volume); thus the mass concentration of a component in a mixture can be called the density of a component in a mixture.
The gram per cubic centimetre is a unit of density in the CGS system, and is commonly used in chemistry.It is defined by dividing the CGS unit of mass, the gram, by the CGS unit of volume, the cubic centimetre.

MLSS (g/L) = SV [mL/L]/SVI [mL/g] or SVI [mL/g] = SV30 [mL/L]/MLSS (g/L) Where: SVI = sludge volume index (mL/g) SV30 = Volume of settled solids per 1 litre after 30 minutes In fact SVI is a calculation from two analyses : SV30 and MLSS. 0=(Q+Q r)(X')-(Q r X' r +Q s X' r) Where: Q = wastewater flow rate (m 3 /d) Q r = return sludge flow rate (m ...
The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
