## Description

The Molecular Weight Calculator is a physics/math tool designed to find the average molecular weight (MW) of molecules by inputting their chemical formulas.

Features:
- Instant calculation
- Results can be copied to other apps
- Includes formula references
- Supports up to 16 decimal places
- Works seamlessly on both iPhone and iPad.
- Lightweight, compact app optimized for everyday use.
- Ad-free and built with privacy in mind.

Note: Chemical formulas are case-sensitive (e.g., C22H30N4O).

Definitions:
- Molecular mass (molecular weight): The mass of one molecule of a substance, expressed in unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
- Molar mass (molar weight): The mass of one mole of a substance, expressed in grams per mole (g/mol).
