What is Molar Concentration?
In Chemistry, the molar concentration or molarity of a solute is the measure of its concentration within a given volume of some kind of solution. Molarity is also the concentration of any molecular, ionic, or atomic species within some specified volume. The SI units for molarity are given as mol/m3. The molarity of a substance is given by the following mathematical equation: c = n/V = N/(NA*V) = C/NA where c is the molarity of the substance, n is the amount of solute in moles, N is the number of molecules in a given volume V, V is the volume being measured, C is the number concentration, and NA is Avogadro’s number (6.023*1023 mol-1). Each of these three equations is a way of arriving at the molar concentration of a given substance with whichever variables one is likely to have at hand to work with. For non-thermodynamic applications in chemistry, the molarity of a substance can be a useful measure. To prepare a 200 millilitre solution of salt water (NaCl) with a molarity of 2 mol/m3,
