What is the Molecular Weight Calculator?
The molecular weight finder is a vital tool for finding the sum of atomic weights. Finding the atomic weight of all the atoms in a molecule becomes hard sometimes but it is not more difficult as our Molecular Formula Calculator is here to give you a helping hand.
Our Mole Weight Calculator eases the hard steps and makes it simple for you. Before proceeding you have to know what is molecular weight. Which we are going to explain to you now.
What is molecular weight?
Molecular weight is defined as the sum of atomic weights of all the atoms in a molecule or a compound. Molecular weight is also named as molecular mass or relative molecular mass. Molecular weight is usually expressed in Da or amu. For example, the molecular weight of an H2O molecule is the sum of the atomic weights of two hydrogen atoms and one oxygen atom.
Find the mass of each element in the molecule i.e., H2O using our molar mass formula calculator.
Molecular Weight Formula used by MW calculator:
Finding molecular weight for complex compounds is a difficult task. But let's make it easy for you by telling you the formula that our molecular weight calculator uses.
Molecular weight = (number of atoms of 1st element)(1st element’s atomic weight) + (number of atoms of 2nd element)(2nd element’s atomic weight) and so on.
If the number of elements in a molecule is more then the formula will be continued. The formula will be continued till the last element.
To determine the atomic weight/ atomic mass of each element, utilize our mass of atoms calculator.
Why is molecular weight important?
Finding the molecular weight of a molecule or a compound is important because of several reasons. Some of them are as follows:
- In polymers, molecular weight affects the physical, mechanical, and chemical properties which means that higher polymers have better mechanical strength and higher melting point. They also have high resistance but their viscosity becomes high due to which processing becomes difficult.
- For bioactive polymers, molecular weight determines the pharmaceutical compound’s release rate in vitro.
- Performance materials are produced because of molecular weight measurements.
Calculating molecular weight using molecular weight finder:
Calculating molecular weight using a molecular weight calculator or doing it manually will give you the same answers. Finding molecular weight using our Molecular Formula Calculator is easy but you should also know how to find it manually. So here are some examples that will help you know it.
Example 1: Find the molar mass of CuSO4
To find the molar mass / molecular mass of CuSO4, we will multiply each atom’s atomic mass by the number of atoms in the molecule. So, the molar mass of CuSO4 will be calculated as:
CuSO4 = (1)(63.55) + (1)(32.07) + (4)(14)
63.55 + 32.07 + 64
159.62 g/mol
So, the molecular mass of CuSO4 is 159.62 g/mol.
Example 2: Find the molar mass of Na2SO4
To find the molar mass / molecular mass of Na2SO4, we will multiply each atom’s atomic mass by the number of atoms in the molecule. So, the molar mass of Na2SO4 will be calculated as:
Na2SO4 = (2)(23) + (1)(32.07) + (4)(16)
46 + 32.07 + 64
142.07
So, the molecular mass of Na2SO4 is 159.62 g/mol.
Similar: To determine the composition of elements in the Na2SO4 use our Calculator for percent composition.
Finding our Molecular Formula Calculator:
To find an online molecular weight calculator open your Google browser and click on the search bar. Enter "molecular weight finder" after that, and check it out. You will see so many calculators in line. Some of them may ask for money to calculate your query so you can choose our weight molecular calculator. Now you have got an online calculator in your service. Now we are going to tell you how to use it.
Using our Mole Weight Calculator:
When you click on our mw calculator you will see the calculator in front of you. There would be an input section. In the input section, you will write the Molecule for example CuSO4. Our Molecular formulas calculator has the button "calculate" to initiate the calculations.
Our molecular weight calculator will take a couple of seconds and then you will see the answer on your screen. There would be “count” which means the number of atoms and the atom will also be present in front of it. For example, in CuSO4 only 1 atom is present in Cu so you would see 1 with Cu. Beneath it, there would be the molecular weight of the molecule written. If you want to know the atomic mass then it would also be there.
Suggested: If your question is about converting and then finding the molecular weight then utilize our atoms to moles converter.
