Editorial Guidelines & Scientific Review

1. Scientific Data Sourcing

All standard atomic weights and chemical constants used in GramToMol calculators originate directly from peer-reviewed, internationally recognized authoritative bodies:

• Atomic Weights: Commission on Isotopic Abundances and Atomic Weights (CIAAW) under the International Union of Pure and Applied Chemistry (IUPAC).
• Avogadro Constant: Bureau International des Poids et Mesures (BIPM) 2019 SI redefinition (exact: 6.02214076 × 10²³ mol⁻¹).
• Gas Constants & STP: IUPAC Standard Temperature and Pressure definitions (273.15 K, 100 kPa, molar gas volume 22.71098 L/mol).

2. Algorithmic Verification Protocol

Every calculator deployed on GramToMol must pass automated unit testing before reaching production:

• Polyatomic & Hydrate Parsing: Rigorous validation against complex formulas including hydrates (e.g. CuSO₄·5H₂O) and multi-bracket structures (e.g. [Pt(NH₃)₂Cl₂]).
• Floating-Point Precision: Rounding operations are maintained at high double-precision internally before formatting to human-readable significant figures.
• Cross-Verification: All formula results are benchmarked against official NIST databases.

3. Author Qualifications & Peer Review

All educational articles, calculation breakdowns, and guides are authored by degreed chemists (PhD or MS in Chemistry) or university faculty. Articles must be independently reviewed by a second analytical or physical chemist on our expert team before publication.

4. Corrections & Feedback Policy

Science education thrives on continuous improvement. If you spot an inaccuracy, formula discrepancy, or unexpected calculation edge case, please reach out directly through our Contact Form. Our chemistry team reviews and resolves reported issues within 48 business hours.
