One of the most commonchemistry calculationsis converting moles of a substance into grams. When you balance equations, you'll use themole ratiobetween reactants and reagents. To do this conversion, all you need is a periodic table or another list of atomic masses. Example:How many grams of ...
How to Convert Gas Volume to Moles The process for converting the volume of an ideal gas to moles is a little different than for mass. You’ll still use a formula, but you do not need the molar mass of the gas for the conversion. ...
A mole ratio is the ratio between the amounts inmolesof any twocompoundsinvolved in achemical reaction. Mole ratios are usedas conversion factorsbetween products andreactants in many chemistry problems. The mole ratio may be determined by examining the coefficients in front of formulas in a ...

Mole, standard unit (6.02214076 x 10^23) in chemistry for measuring large quantities of very small entities such as atoms, molecules, or other specified particles. The number of units in a mole also bears the name Avogadro’s number, or Avogadro’s const
The mole is an important concept for talking about a very large number of things — 6.02 x 1023 of them to be exact. This module shows how the mole, known as Avogadro’s number, is key to calculating quantities of atoms and molecules. It descr
