This project is a Java-based Molecular Weight Calculator that interprets and calculates the molecular weight of any given chemical formula, such as "H2O", "C6H12O6", and more.

• Enum Storage for Chemical Elements: The project stores chemical elements in Enums, which makes it easy to manage and extend in the future.
• Formula Interpreter: It accepts a chemical formula string (like "H2O") and intelligently parses it to compute the weight.
• Error Handling: Throws an IllegalArgumentException when it encounters an unknown element symbol or if the formula pattern does not match the expected format.
• User Interaction: A simple command-line interface to input the chemical formula and get the molecular weight as an output.

1. Clone the repository to your local machine.
2. Compile the MolecularWeightCalculator.java file.
3. Run the program.
4. When prompted, enter your chemical formula.
5. Receive the molecular weight of the given formula in g/mol.

Note: Make sure that the chemical formula follows the pattern of element symbols, optionally followed by a number indicating the count of atoms for that element. If no number is provided, it is assumed the element appears once in the molecule.
