Molar Mass

Subject: Chemistry

Book: General Chemistry

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It is derived by summing the atomic masses of the elements in a compound. For instance, CO2 has a molar mass of about 44.01 g/mol (12.01 for C + 2×16.00 for O). Molar mass is critical for converting between mass, moles, and number of particles in chemical calculations.
