🧪 molweightcal

molweightcal is a Python package to calculate the molecular weight of a chemical compound given its molecular formula (e.g., H2O, C6H12O6, (NH4)2SO4).

Features

✅ Provides step-by-step calculation for each element ✅ Supports all known elements ✅ Lightweight and fast — no external dependencies

🔧 Installation

pip install molweightcal

🚀 Usage

import molweightcal

print(molweightcal("C6H12O6"))

✅ Output

Molecular weight of C6H12O6: 180.156 Details: C(6) × 12.011 = 72.066 H(12) × 1.008 = 12.096 O(6) × 15.999 = 95.994

❗ Error Handling

molweightcal performs thorough input validation to detect and report issues such as:

✅ Unknown chemical elements (e.g., "Z6H2") ✅ Lowercase letters in invalid positions, etc.
