For a given element, the mass (in grams) of one mole is given by its mass number on the periodic table; the "molar mass" of a molecule is the sum of the molar masses of the elements in the molecule in the correct ratios. It is simple to determine the molar mass of elements and ...

How do intermolecular forces and kinetic energy interact to determine at what point a liquid will boil?Intermolecular Forces:Intermolecular forces are attractions between neighboring molecules that help determine the melting and boiling points of substances. The three...
Titration is used to determine the concentration of an unknown substance via the molar relationship expressed through the chemical reaction equation. Using these relationships, the pH value can be determined by calculating the concentration of hydrogen i
Explain how you could use the melting point to determine the purity of a solid sample. What effect does the sample size of the melting point have on the melting point? Why do impure molecule have lower melting points? Explain the simple criteria of purity and melting point. ...
Bottom Line: Use Relative Electronegativities, Not Formal Charges, To Determine Electron Densities Notes 1. How Do We Tell Where The Electrons Are? First, Draw The Lewis Structure OK. Let’s start with the first question: how do we tell where the electrons are in a molecule? The first ...
Allergists use a variety of diagnostic techniques to determine if a person is allergic. Unfortunately, the safest and often the most effective tests are not completely reliable by themselves in identifying if a substance is the cause of a patient's symptoms. The most common test, the scratch te...
, by the boiling point of the solvent) and is often not sufficient to overcome the energy barrier. For this reason, colloidal dispersions are commonly destabilized by lowering the energy barrier. In charge-stabilized dispersions, this can be done by modulation of the Debye length and thus the...

Flavorings are made from precise mixtures of synthetic or natural chemicals. If they're mixed incorrectly or in the wrong quantity, the flavoring will not produce the desired flavor. So how do flavorists learn what chemicals make up particular flavors? How do they determine a flavor's correct...
