FREE EDUCATIONAL SOFTWARE MOLECULAR WEIGHT ESTIMATOR

Features:

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. 

How to start with Molecular weight estimation software ?

• 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.

Sample formulas

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.

• Now you get answers to all the questions as below.

  • Molecular mass = 169.825 grams

  • The contents are displayed as below.

  ELEMENT	ATOMIC WEIGHT	QUANTITY	% WEIGHT

EXAMPLE - 3

• What is the molecular mass of Ca(OH)₂ ? Give the split-up of % mass shared by each constituent element.

• Type "Ca(OH)2" 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 Ca(OH)₂

• 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 = 74.093 grams

  • The contents are displayed as below.

  ELEMENT	ATOMIC WEIGHT	QUANTITY	% WEIGHT
  CALCIUM (Ca-20)	40.078	1	54.09%
  OXYGEN (O-8)	15.9994	2	43.19%
