Molarity Tim Loftus A number of lab-prepared solutions in the wastewater laboratory are measured in molarity M. It is one of the ways to measure the concentration of an element, ion, or compound in solution. The potassium chloride solution used to calibrate a conductivity meter and the standard sodium chloride solution for chloride analysis are typically measured in molarity. A mol is the gram-atomic or molecular mass of an element or molecule and is a measure of the number of atoms or molecules. For example, from the periodic chart, the gram-atomic mass of hydrogen is 1. One gram of hydrogen is one mol and contains 6. The gram-atomic mass of oxygen is Sixteen grams of oxygen is one mol and also contains 6. Even though the masses are different, one mol of each element contains the same number of atoms. This same concept is also used to determine the mol of a compound. Eighteen grams of water is one mol and contains 6. Using the mol as a measurement tool is especially helpful when determining how much of one compound or element reacts with another.

London dispersion forces increase with increasing atomic mass. Iodine is a solid while bromine is a liquid due to the greater intermolecular interactions between the heavier iodine atoms. In dental amalgam, the mercury atoms are locked in a solid phase that does not undergo corrosion under physiological conditions; hence, the mercury atoms cannot readily diffuse to the surface where they could vaporize or undergo chemical reaction.

Concentration is an expression of how much solute is dissolved in a solvent in a chemical solution. There are multiple units of concentration. Which unit you use depends on how you intend to use the chemical solution. The most common units are molarity, molality, normality, mass percent, volume percent, and mole fraction. Here are step-by-step directions for calculating concentration, with examples showing the math and tips on when to use the units. Molarity is one of the most common units of concentration. It is used when the temperature of an experiment won't change. It's one of the easiest units to calculate. You get the mass of solute for the solution, mix the solute with a known volume of solvent, and divide mass by volume for concentration. Calculate Molarity : moles solute per liter of solution not volume of solvent added since the solute takes up some space.

To define a solution precisely, we need to state its concentration: how much solute is dissolved in a certain amount of solvent. Words such as dilute or concentrated are used to describe solutions that have a little or a lot of dissolved solute, respectively, but these are relative terms whose meanings depend on various factors.
