Compounds are weighed using scales to yield grams. It's often necessary to convert grams to moles for chemistry calculations.Peter Muller / Getty Images Learn how to convert the number of grams of a molecule to the number of moles of the molecule with examples below. This type of conversion ...
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....
Moles of Solute Say you create a solution with 200 grams of table salt. One mole equals the molar mass of the solute which is 58.4538 grams. Divide the mass of the solute by the molar mass to get the number of moles of solute. In this case, work out 200 ÷ 58 = 3.4483 moles of...
The mass of an element or molecule in atomic mass units is equal to the mass of a mole of the same particles in grams. Divide the number by 1,000 to get the molar mass in kilograms. What Is a Mole? A mole is a very large number of atoms or molecules. This large number, known ...
Once the maltose is broken into glucose, other enzymes act on the glucose molecules to turn them into energy for the cell to use. To make an enzyme that it needs, the chemical mechanisms inside an E. coli cell make a copy of a gene from the DNA strand and use this template to form...
How to remove ions from water Ions: Ions are atoms or molecules that have charge due to their excess or lack of electrons in their structure. An atom with an excess of electrons is considered a negative ion (anion), while lacking electrons on their structure will give a positively charged ...

or the molarity. A mole is a term which stands for 6.02 x 10^23 atoms or molecules of chemical. Another less common unit of concentration is molality. Molaility is the moles chemical per kilogram of solvent used in making the solution. You can convert from molarity to molality if you kno...
What is a mole, and how do you convert from grams to moles? How does this relate to Avogadro's number? Mole: Mole is a technical term that is used to explain how much mass of material contain 6.023×1023 (Avogadro's number) atoms. In other words,...
4. Moles and Molar solutions (unit = M = moles/L) Sometimes it may be more efficient to use molarity when calculating concentrations. A mole is defined as one gram molecular weight of an element or compound, and comprised of exactly 6.023 x 10^23 atoms or molecules (this is called Avag...
