Question

How can molarity be used as a conversion factor?

Answer 1

Molarity is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution.

Complete step by step answer:
Molar concentration or molarity is expressed in units of moles of solute per liter of solution. It is defined as the amount of substance of solute per unit volume of solution, or per unit volume of solution, or per unit volume of solution, or per unit volume available to the species.
$C = \dfrac{n}{v} = \dfrac{N}{{{N_A}V}} = \dfrac{C}{{{N_A}}}$
$n \to$ amount of solute in moles
$N \to$ number of constituent particles.
$V \to$ Volume in liters
${N_A} \to$ Avogadro constant.
$\dfrac{N}{V} = C \to$ number density.
The $SI$ unit of molarity is $\dfrac{{mole}}{L}$
In thermodynamics the use of molar concentration is after not convention because the volume of most solutions slightly depends on temperature due to thermal expansion. The sum of molar concentration gives the total molar concentration, namely the density of the mixture divided by the molar mass of the mixture or by the reciprocal of the molar volume of the mixture.
The coherent unit for molar concentration is $mol/{m^3}.$ The unit is after denoted as $M.$

Additional Information:
If a molecule entity dissociates in solution the concentration refers to the original chemical formula in solution the molar concentration is sometimes called formal concentration or formality or analytical concentration. The ability of one compound to dissolve in another compound is called solubility. When a liquid can completely dissolve in another liquid the liquids are miscible. A solution is a homogeneous mixture; a solute is a substance dissolved in another known as a solvent. One important parameter of a solution is the concentration, which is a measure of the amount of solute in the given amount of solution or solvent. The physical properties of compounds such as melting point and boiling point change when other compounds are added. Together they are called colligative properties. There are several ways to quantify the amount of one compound dissolved in other compounds collectively, called concentration.

Note: In an ionic solution, domic strength is proportional to the sum of the molar concentration of salts. As molarity is dependent on volume and volume rises as temperature increases. Molarity is inversely proportional to temperature so as the temperature increases molarity decreases. At some point the energy ions outweigh the entropy gain and no more solute particles can be dissolved; the solution is solid to be saturated. The point at which a solution can become saturated can change significantly with different environmental factors, such as temperature, pressure and contamination. The greater the temperature of the solvent, the more a given solid solute it can dissolve. Molarity largely depends on the solute and solvent.
