Mole Calculator

Use this mole calculator to find how many moles, molecular weight, and molar mass are required for your experimental measurements. 

What Is A Mole?

The Mole is an amount unit similar to pair, dozen etc. and it contains \(6.02214076 * 10^{23}\) number of particles, whereas this number (\(6.02214076 * 10^{23}\)) is called the Avogadro’s Number or Avogadro’s Constant.

Large quantities of tiny entities such as atoms, molecules, or other specified particles are measured in Mole (also spelled as mol).

Mathematical Equation:

Molecular Weight Or Molar Mass:

It is the intrinsic property of an element and is based on its atomic mass which is further based on the number of protons and neutrons in that element.

The molar mass of a compound is simply a proportionate sum of the molecular weights of its constituent elements. Knowledge of molar mass is essential for mole conversions but calculating molar mass is a very detailed task and requires rigorous use of a periodic table. 

For convenience, you can use the Molar Mass Calculator. It makes the calculations for finding the number of moles quicker and more precise. 

How To Calculate Moles? 

To calculate moles, use the following formula:

\(\ Number\ of\ Moles = \dfrac{Mass\ of\ Substance}{Molar\ Mass\ of \ Substance}\)

It is evident from this mathematical expression that we need to know any of the 2 variables to compute the third value.

To precisely convert grams to moles, you can use our grams to moles calculator which facilitates smooth conversions from grams to moles. 

Use our moles to grams calculator to determine the mass of a substance in grams or rearrange the above-mentioned equation as below:

\(\ Mass =\ Molecular\ Weight\times \ Mole\)

Relatively complex problems involving large amounts of masses and molar masses can be solved precisely using the mole calculator.

FAQs:

How Do You Find Moles Using Avogadro’s Number?

The conversion between the molecules and moles is done by using the Avogadro’s number as below:

• For converting moles to molecules, multiply \(6.02214076 * 10^{23}\) by the number of moles
• For converting molecules to moles, divide the number of molecules by \(6.02214076 * 10^{23}\)

How Many Atoms In A Mole?

One mole contains the following number of atoms:

\(\ 6.02214076 * 10^{23}\) 

Why Do We Calculate Moles?

It helps to calculate how many molecules or particles are present in the given mass of a substance. With the help of it, chemists determine the amount of reactants needed for chemical reactions. It’s a common unit of concentration. Therefore it is used widely in chemistry. 

How To Convert Molecules To Moles?

Use the following formula for converting molecules to moles:

\(\ mol =\dfrac{molecules}{6.02214076 × 10^{23}}\)
