Understanding Molar Mass
The molar mass of a substance is the mass of one mole of its molecules or atoms, measured in grams per mole (g/mol). A mole is a fundamental unit in chemistry that represents a specific number of particles, usually Avogadro’s number, which is approximately \(6.022 \times 10^{23}\). For molecular compounds like water, the molar mass is calculated by summing the atomic masses of all atoms in a molecule.
The atomic mass of each element is measured in atomic mass units (amu), and the molar mass is simply the total mass of one mole of these atoms expressed in grams. For water, this means adding the atomic masses of two hydrogen atoms and one oxygen atom.
