Put values to convert grams to moles in input box using this Mole Calculator.
mole =mass/molecular weight
Are you struggling with questions like How to find/calculate moles? How to find moles from grams? How to convert grams to moles? Well, don’t worry! We have got it sorted out for you.
No need to thank, just pay some cash, just kidding, good feedback is all we ask.
Although the name of this calculator is the Mole calculator, in reality, it does much more than that! Using this awesome converter you can convert moles to mass and grams, grams to mass and moles, and last but not least mass to moles and grams.
We couldn’t name it as “moles, mass, and grams calculator”. That would have been a mouthful. But it is designed for all these works.
Before I tell you how to use this calculator, let’s first learn about this topic.
In chemistry, we are weighing substances continuously to perform reactions. We all know how tiny and invisible an atom is. So when we are doing some experiments in the lab, we cannot use kilograms or grams in the procedure.
It is said because it would have made reactions much more difficult especially on a large scale. I’ll give you an example. Consider we need to know how many carbon atoms are in 12 grams of carbon. Although we know it’s roughly 6.02*1023atoms. But using this value in calculations is very difficult.
This is why scientists needed to come up with a unit of measurement that would account for a large number of atoms, ions, and molecules. Because they are so small that there is an inconveniently large number of them in a single gram.
This is where Mole was introduced in chemistry. It is an SI unit for the amount of a substance. It is represented by “mol”.
Wondering how much is a mole? It means 6.02*1023, which is also Avagadro’s number. A mole of a substance represents Avogadro’s number of particles in it whether they exist in a free atomic state, in the form of molecules or ionic form.
There is no rocket science in it. Scientists could have used any element as standard. But Amedeo Avogadro chose carbon. Don’t worry too much about it.
The molecular weight of a molecule is the total weight of elements present in it. For example, if we want to calculate the molecular weight of benzene C6H6.
Atomic mass of one carbon = 12 u
Atomic mass of one Hydrogen = 1.008 u
Atomic mass of benzene = 6*12 + 6*1.008
= 78.048 u
After using our smart mole conversion calculator, you will be able to convert moles to atoms, molecules, and grams (g).
Firstly: Choose what you want to calculate. For example, let’s say you want to find molecular weight.
Secondly: Enter the required values in respected places. In this case moles and mass.
Lastly: Click calculate.
There you go, How fastly and easily this smart calculator calculated molecular weight using the formula for you! Not only that but also provide you with the whole procedure. On the topic of a good calculator, spare a minute to check our yield calculator.
Now let’s learn the concept of mole and its application through examples.
How many moles are in 16 grams of oxygen gas?
Mass of oxygen = 15.999 =16 grams
Molecular weight = ( as oxygen exists in a molecular state in gaseous
form) 2 * 16 = 32 g/mol
Mole = 32/32
It has one mole.
Moles = 13
One molecule of fluorine = 2 atoms
As one mole has Avogadro’s number of particles and in a gaseous state, fluorine atoms form a molecule of 2 atoms. So,
One mole has 6.02*1023molecules.
13 moles have 13*6.02*1023molecules.
Finally, 13 moles have 2*13*6.02*1023atoms. Which are1.5652*1025 atoms.
Calculate moles for 5 grams of nitrogen atoms.
Mass = 5grams
Molecular weight = 14 g/mol
Now using the mole formula,
mole =mass/molecular weight
It has 0.357 moles.
Calculate ions of sodium and chloride in 20 grams of NaCl.
Mass = 20
Molecular weight = 58.44 g/mol
Converting grams to moles.
It has 0.34 moles.
Now as we know one mole has Avogadro’s number of particles.
Molecules of NaCl = 0.34 moles6.02*1023
Ions in one molecule = 1 Na+ + 1 Cl-
= 2 ions
Total ions in 20 grams of NaCl= 22.0468*1023
In which there are
Na+ions = 2.0468*1023molecules.
Cl-ions = 2.0468*1023molecules.
To find the molar mass of gaseous compounds, use our molar mass of gas calculator.
One mole is equal to 114.818 grams.
There is Avogadro’s number of molecules in a gram.
It varies for every element. We’ll have to calculate moles and multiply it by 6.02*1023 to find atoms.
No, they represent two different matrices. Molecular mass is the molecular weight, atomic masses of all the elements in a molecule added together, of a molecule while molar mass represents the weight of one mole of a substance.
