Mole formula


Mole =Mass/Molecular weight

Are you struggling with questions like how to convert moles to grams, how to find moles, or how to find moles from grams? Well, don’t worry! We have got it sorted out for you.

By using this moles to grams calculator, you can convert moles to mass and grams, grams to mass and moles, and last but not least mass to moles and grams.

In this space, we will cover mole definition, moles formula, how to convert grams to moles without using grams to moles calculator, and some examples to convert mass to moles, etc.

What is a Mole?

Mole is an SI unit for the amount of a substance. It is used to measure substances in small quantities. It is represented by “mol”.

Wondering how much is a mole? A mole of an element or molecule contains exactly 6.02214076×1023 particles. This number is also referred to as Avogadro’s number.

For example:

  • One mole of helium gas is equal to 02×1023atoms.
  • One mole of oxygen is equal to has 02×1023 molecules.
  • One mole of NaCl has 02×1023Na and 6.02×1023 Cl ions.

How to calculate moles?

Converting grams to moles is super easy if you use mass to moles calculator above. On the other hand, if you are interested in mole calculation without using atoms to grams calculator, follow the examples below.

Example:

How many moles are in 16 grams of Oxygen gas?

Solution:

Step 1: Write down and identify the values.

Mass of Oxygen =16 grams

Molecular weight = 2 × 16 = 32 g/mol

in one molecule of oxygen there are 2 atom.

Step 2: Apply formula as shown below or place the values in moles to atoms calculator.

Mole =mass/molecular weight

Mole = 16/32 = 0.5

16 grams of Oxygen has 0.5 moles.

Use moles to grams converter to verify the number of moles in the above example. To find the molar mass of gaseous compounds, use our molar mass of gas calculator.

FAQs

How many grams are in a mole?

One mole can have varying quantity in grams depending on the element. Each element or substance has different mass and molecular mass. A mole depends on both mass and molecular mass.

How many molecules in a mole?

A mole contains 6.02214076×1023 numbers of molecules.

How many atoms in a gram?

It varies for every element. You’ll have to calculate moles and multiply it by 6.02*1023 to find atoms. You can also use molecular formula calculator to calculate moles for chemistry numerical.

Are molar mass and molecular mass the same?

No, molar mass and molecular mass are not same. They represent two different matrices.
