The mole (symbol: mol) is the unit of measurement for amount of substance in the International System of Units (SI). It is defined as exactly 6.022 140 76 × 1023 particles, which may be atoms, molecules, ions, or electrons.

One mole of atoms contains 6 x 1023 atoms, no matter what element it is. This is a very large number: it is 6 with 23 zeros after it. It is known as the Avogadro number. This number is used in. The mole is equal to Avogadro's numb. The mole is a unit of measure for the amount of a chemical substance.

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: Behringer usb audio driver 2.8 40.
- 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 molesis super easy if you use mass to moles calculatorabove. 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 calculatorto 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.

There are about 20 species of fuzzy moles (the kind that crawl around on the ground), and one kind of mole that might appear on your face, but today is a day for celebrating a different kind of mole. Today’s mole is a unit — one invented by a man named Avogadro.
Really, a mole is just a group of objects. You can think of “a mole” the same way you think of “a dozen.” You’re probably familiar with a dozen eggs, or chickens or planets. Moles are no different. You can have a mole of molecules or people or cheeseburgers. But there are a lot more than twelve things in a mole — there are 6.02 x 1023. That’s 602,000,000,000,000,000,000,000 things. Because the mole contains so many units, they’re most often used in chemistry is a way of measuring really really small things like atoms or molecules.
So a mole of water is 6.02 x 1023 molecules of water, which works out to be about 18 grams, or 18 mL. A mole of aluminum is about 26 grams. But to really appreciate how many molecules are in a mole it helps to think about things we can see. To do that, let’s try these comparisons from Daniel Dulek’s lesson about how big a mole is.
A way to think about the relative size of a mole?
If you had a mole of doughnuts, they would cover the entire Earth in a doughnut-layer five miles deep.
If you had a mole of basketballs, you could create a new planet the size of the Earth!
If you received a mole of pennies on the day you were born, and spent a million dollars a second until you died at 100, you’d still have over 99.99% of your money in the bank.
One mole of red blood cells is more red blood cells than exist in every human on earth right now. A mole of cereal boxes stacked end to end would reach from the Sun to Pluto 7.5 million times. A mole of turkeys could form sixteen earths.
Okay, so now that we know why a mole has 6.02 x 1023 things in it, what can we do with that information? Moles in chemistry are far more useful than moles in the ground, or on your face. They factor into all kinds of equations and important concepts in chemistry. Chemists think of moles or atoms like you and I think of a dozen eggs – we add them to recipes, order them from the store and calculate what we need based on how many we have.

What would a mole of fuzzy moles look like? Well, the pile of animals would weigh a little over half of the mass of our moon. Thankfully, there’s no chemistry equation in the world that calls for that many mammals. But if there was, you’d now know just how many mammals that would be.
