Finding the number of moles can be done with the following formula:
Your result will be the total number of moles which can also be converted into millimoles or micromoles by selecting those options from the dropdown menu.
The steps to use the mole calculator include:
Let's say you have a scenario where the mass is 5 grams and the molecular weight is 7 grams per mole, you can use this tool to find the number of moles. We enter 5 into the mass field and leave the unit as grams, then we enter 7 into the molecular weight field and leave the unit as grams per mole.
We can now hit calculate to get our answer of .7143 moles, which can be converted into 714.2857 millimoles or even 714,285.7143 micromoles.
An Italian scientist, Amedeo Avogadro, came up with the size of a mole. He discovered that the number of atoms in 12 grams of carbon-12 is 6.02 x 1023. It has since been widely accepted as the number of atoms or entities in one mole of a substance.
Atoms, molecules, particles, and other units of measurement in chemistry are often measuring very small amounts of a certain substance or property. The mass of these variables are often next to none, making moles the best way to measure them.
The average mass of one mole of H2O is 18.02 grams.
