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 dropdown menu.
You can see that the software finds out the molecular weight and shows the splitup 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 H_{2}SO_{4} ? Give the splitup 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 splitup 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 H_{2}SO_{4}
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

OXYGEN (O8)  15.9994  4  65.25% 
EXAMPLE  2
What is the molecular mass of N_{2}Cl_{4} ? Give the splitup 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 splitup 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 N_{2}Cl_{4}
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.
