Learning how to calculate molarity isn't difficult; the key is to remember the units of molarity (M): moles per liter. Find the molarity by calculating the number of moles of the solute dissolved in liters of a solution. Molarity is a unit of concentration, measuring the number of moles ...
Moles and Equivalents The equivalent unit was introduced to account for the fact that when solutes dissolve in solvent to create a solution, the number of particles dispersed depends on the valence of the solute. For example, when one molecule of KCl dissolves, it leaves two ions, or charged...

The number of moles of a species from its volume is calculated by using two important values: (1) density and (2) molar mass of the species. Using the density, the mass of the species corresponding to its volume is calculated. Using the molar mass, the corresponding number of moles of ...

Grams to Moles Find the number of gramsof the substance. You will know from the problem how many grams and what the substance is, for example, 12 g of water. Find the molecular weight of each atom in the substance. The molecular weight is how much each molecule of the substance weighs...
Finally, to obtain molarity, which is defined as moles of solute per liter of solution, we would simply divide the moles by the liters. Here is an example: If a solution contains 0.10 g NaCl in 1.0 ml of solution, what is the molarity? Molar mass of NaCl = 58 g / mole...

But the units are no longer moles/L, but rather millimoles/L or mmol/L. These units are called millimolar or mM. While in many cases scientists prefer to talk about concentration in terms of molarity, it can sometimes be more useful to talk about mass per liter solvent. For example, ...
