Thus M = mol per L. All mole calculations will determine the amount in moles of the solution, for which it is the molar concentration. The number of moles of a substance in one litre of solution is called its molarity. The official symbol for molarity is “c” (concentration), but most people use the symbol “M”.

The number of moles of solute in solution is given by the formula.

c (HCl) = 0.01 mol L -1 (c stands for concentration, formula given in round brackets or parentheses) Equation (formula or expression) to calculate the molarity of a solution (concentration in mol L -1) is. c = n ÷ V. Using the formula triangle gives three useful formulae: \[concentration = \frac{{no.\,of\,moles}}{{volume}}\] \[volume = \frac{{no.\,of\,moles}}{{concentration}}\] The relationship between two solutions with the same amount of moles of solute can be represented by the formula c 1 V 1 = c 2 V 2, where c is concentration and V is volume. Key Terms dilution : The process by which a solution is made less concentrated via addition of more solvent. The concentration unit, formal, is similar to the more familiar molar concentration in that it is calculated as the number of moles of a substance in a liter of solution. Formal concentrations are notated with the symbol F, and are formula weights per liter of solution. A formula weight is the weight of a mole of the substance.

This is also referred to as molality, which is defined as the number of moles of solute dissolved per kilogram of solvent (mol/kg = m). Once the researcher had obtained this information, the researcher was then able to apply the following formula to work out the primer concentration in moles/liter [1]. Concentration in moles/liter (C) = (dilution factor × A260) ÷ (sum of extinction coefficient contributions × cuvette path length) For our example, that would be: Concentration = moles / volume Concentration is given in mol/dm 3, properly written as moldm -3 but this notation is often not used until post-16 level. moldm -3 is often abbreviated to M, as it is easier to write, especially labelling a bottle, but for assessments, students should be encouraged to use the full notation.
