FREE EDUCATIONAL SOFTWAREMOLECULAR WEIGHT ESTIMATOR |  |
The Molecular weight estimator is a Free chemistry software, which facilitates for the quick estimation of the molecular weight from any molecular formula. This software also gives the split-up of the weight being contributed by its constituents along with their percentage share.

Open Genius Maker software and click "Molecular weight" button. It opens the Molecular weight window as shown above.
Certain molecular formula are entered in the software by default for your easy understanding.
Just select any molecular formula from the drop-down menu.
You can see that the software finds out the molecular weight and shows the split-up of weight shared by its constituents.
You may click the "Show syntax" button to see the sample molecular formulas and the way to enter them on to the software.

EXAMPLE - 1
What is the molecular mass of H2SO4 ? Give the split-up of % mass shared by each constituent element.
Type "H2SO4" in the formula box.
As you type the formula, then and then the software tries to interpret the typed text as formula and estimates the weight and split-up of constituents. These information are updated in the sections below the formula box. The section immediately beneath the formula bar indicates the exact molecular formula as interpreted by the software from your typed text.
After typing the above text, you will see that the software has automatically interpreted the typed text as H2SO4
Click "Evaluate" button. The colour of the contents box changes from a fade colour to bright colour, indicating that the software could interpret the typed text successfully into a formula.
Now you get answers to all the questions as below.
Molecular mass = 98.078 grams
The contents are displayed as below.
ELEMENT | ATOMIC WEIGHT | QUANTITY | % WEIGHT |
| HYDROGEN (H-1) | 1.00794 | 2 | 2.06% |
| SULPHUR (S-16) | 32.065 | 1 | 32.69% |
| OXYGEN (O-8) | 15.9994 | 4 | 65.25% |
EXAMPLE - 2
What is the molecular mass of N2Cl4 ? Give the split-up of % mass shared by each constituent element.
Type "N2Cl4" in the formula box.
As you type the formula, then and then the software tries to interpret the typed text as formula and estimates the weight and split-up of constituents. These information are updated in the sections below the formula box. The section immediately beneath the formula bar indicates the exact molecular formula as interpreted by the software from your typed text.
After typing the above text, you will see that the software has automatically interpreted the typed text as N2Cl4
Click "Evaluate" button. The colour of the contents box changes from a fade colour to bright colour, indicating that the software could interpret the typed text successfully into a formula.
