  • mole
  • The molar volume, symbol Vm, is the volume occupied by one mole of a substance (chemical element or chemical compound) at a given temperature and pressure. (wikipedia.org)
  • Multiplying by the molar mass constant ensures that the calculation is dimensionally correct: standard relative atomic masses are dimensionless quantities (i.e., pure numbers) whereas molar masses have units (in this case, grams/mole). (wikipedia.org)
  • It can also be defined as follows: Molar conductivity of a solution at a given concentration is the conductance of the volume (V) of the solution containing one mole of electrolyte kept between two electrodes with area of cross section (A) and at a distance of unit length. (wikipedia.org)
  • Molar pregnancies are categorized as partial moles or complete moles, with the word mole being used to denote simply a clump of growing tissue, or a growth. (wikipedia.org)
  • Or more simply: 1 molar = 1 m = 1 mole/litre. (wikipedia.org)
  • Molar refractivity, A {\displaystyle A} , is a measure of the total polarizability of a mole of a substance and is dependent on the temperature, the index of refraction, and the pressure. (wikipedia.org)
  • In chemistry, the standard molar entropy is the entropy content of one mole of substance under a standard state (not STP). (wikipedia.org)
  • The standard molar entropy is usually given the symbol S°, and has units of joules per mole kelvin (J mol−1 K−1). (wikipedia.org)
  • The standard molar entropy of a gas at STP includes contributions from: The heat capacity of one mole of the solid from 0 K to the melting point (including heat absorbed in any changes between different crystal structures) The latent heat of fusion of the solid. (wikipedia.org)

  • S 0 = K s p x x y y ( x + y ) {\displaystyle S_{0}={\sqrt[{(x+y)}]{\frac {K_{sp}}{x^{x}y^{y}}}}} If the solubility product constant (Ksp) and dissociation product ions are known, the molar solubility can be computed without the aforementioned equation. (wikipedia.org)
  • Inserting these initial concentrations into the solubility product equation gives: K s p = ( x ) ( 2 x ) 2 = ( x ) ( 4 x 2 ) = 4 x 3 {\displaystyle {\begin{aligned}K_{sp}&=(x)(2x)^{2}\\&=(x)(4x^{2})\\&=4x^{3}\end{aligned}}} If Ksp is known, x can be computed, which is the molar solubility.

  • teeth
  • The molars or molar teeth are large, flat teeth at the back of the mouth. (wikipedia.org)
  • In humans, the molar teeth have either four or five cusps. (wikipedia.org)
  • These mammalian multi-cusped cheek teeth probably evolved from single-cusped teeth in reptilians, although the diversity of therapsid molar patterns and the complexity in the molars of the earliest mammals makes it impossible to determine how this happened. (wikipedia.org)

  • Molar distalization is a process in the field of Orthodontics which is used to move molar teeth, especially permanent first molars, distally (backwards) in an arch. (wikipedia.org)
  • The cause is often the result of loss of E space in an arch due to early loss of primary molar teeth and mesial (forward) migration of the molar teeth. (wikipedia.org)
  • Sometimes molars are distalized to make space for other impacted teeth, such as premolars or canines, in the mouth. (wikipedia.org)
  • Earlier into the field of orthodontics, molar teeth would be distalized with the use of headgears. (wikipedia.org)

  • However
  • However, for historical reasons, molar masses are almost always expressed in g/mol. (wikipedia.org)
  • However, out of the 4 studies reviewed, this was the only study which favored more distalization with unerupted molars, as others did not agree. (wikipedia.org)
  • However, this is impractical for most laboratory purposes and most chemical literature traditionally uses mol/dm3, or mol dm−3, which is the same as mol/L. These traditional units are often denoted by a small caps letter m (pronounced molar), sometimes preceded by an SI prefix to denote sub-multiples, for example: mol/m3 = 10−3 mol/dm3 = 10−3 mol/L = 10−3 m = 1 mmol/L = 1 mm.
