βοΈ What is Molar Mass?
Molar mass is the mass of one mole of a substance, measured in grams per mole (g/mol). It’s calculated by summing the atomic masses of all atoms in a chemical formula.
M = Ξ£(n Γ atomic mass)
Sum of (atom count Γ atomic mass) for all elements
Example: H2O = (2Γ1.008) + (1Γ16.00) = 18.02 g/mol
