This web app is designed to simplify common chemistry calculations. By inputting the amount of a substance, selecting its units (e.g., grams, moles, atoms), and choosing the desired output units, the app quickly converts between key quantities:

• Moles: A fundamental unit for measuring the amount of a substance.

• Mass: The weight of a substance.

• Atoms (or formula units): The number of individual particles present in a sample.

• Molar Mass: The mass of one mole of a substance.

This tool aims to assist students, educators, and anyone who needs to perform these calculations quickly and accurately.
