## What is Chemies?

Chemies turns chemistry calculations into clear, guided steps.

EQUATION BALANCER
Type in a chemical equation and Chemies balances it for you — with the working shown, not just the answer.

CALCULATORS
A focused set of tools for common chemistry problems:
• Formula Mass Calculator — find relative formula mass and molar mass
• Mole Converter — convert between mass, moles, and particles for a single substance
• Empirical Formula — turn experimental mass data into empirical formula
• Mole Calculation — connect reacting quantities through mole ratios
• Dilution Calculator — find concentrations and volumes before and after dilution
• Oxidation Number — work out each element's oxidation number step by step

Every tool shows its working, not just a final number, so you can follow the reasoning and learn as you go.

Built for students and anyone brushing up on chemistry — clean, fast, and distraction-free.
