About this document
Understanding Atomic and Molecular Mass by NguyenHoangMinhDuc is a document available to read on EtoBox.
This document defines key chemistry formulas and concepts: Relative atomic mass (Ar) and relative molecular mass (Mr) refer to the weighted mean mass of isotopes and sum of element masses in a molecule. Molar mass (M) equals relative mass in g/mol. Formulas allow converting between moles, mass, and molar mass. Empirical formulas give simplest whole number ratios, while molecular formulas give actual numbers of atoms bonded. Empirical formulas can be determined from percentage composition or other data.
