Chemistry is full of many different confusing conversions. These conversions are important because they ultimately allow us to discover how a particular atom or molecule will interact with other atoms and molecules. Central to chemical conversions is the conversion of grams to moles, and vice versa....
The definition of a mole is thus the mass of any compound, measured in grams, that equals the masses of the component elements measured in atomic mass units. To calculate the number of moles of a compound you have on hand, you divide the mass by the mass of one mole of the compound,...
Also, when analyzing the solutions chemist use mole formula to measure the concentration of components. Besides, in this topic, we will discuss the definition of this unit and how to calculate it. What is Mole Fraction Simply we can say that this formula refers to the ratio of...
Mole Snacks: +0/-1 How calculate the length of a molecule? «on:November 08, 2013, 04:00:44 AM » Hello! Considering this molecule C-C-O-C-O-C (ommited hydrogen atoms for this example). If i want to calculate her length, i have to consider covalent radius of each atoms or ...
In chemistry, a mole is a unit of measurement used to express the amount of a substance. It is defined as the amount of a substance that contains the same number of particles (atoms, molecules, or ions) as there are in 12 grams of carbon-12. How is the number of ...
Bond enthalpyis the energy required to form or break a given bond. Its value can change between molecules, even for the same type of bond. For example, the bond energy of H2O's two O−H bonds is 464 kilojoules per mole (kJ/mol), but in methanol (CH3OH) the one O−H bond has...
Mole Ratio from a Chemical Formula Vocabulary and Formulas Avogadro's number: Avogadro's number is a very large number, equal to 6.0221409×1023. Mole: A mole is Avogadro's number of atoms or molecules or particles. Mole Ratio General Chemical Formula: AaBbCc... where the capital letters...
How to Calculate Mole Fraction of a Solution Mole fractionor molar fraction is the number of moles of one component of a solution divided by the total number of moles of all chemical species. The sum of all mole fractions adds up to 1. Note that moles cancel out when calculating mole fra...
