What is the mass of one mole of a substance called?

• A. Molar mass
• B. Molecular weight
• C. Atomic mass
• D. Diverse weight

Answer: (A)

The mass of one mole of a substance is referred to as molar mass. It is an important concept in chemistry as it enables chemists to relate the mass of a substance to the amount of substance in moles, which is a fundamental unit in the field of chemistry. Molar mass is typically expressed in grams per mole (g/mol) and corresponds to the substance’s formula mass derived from the periodic table, where the atomic weights of the constituent elements are summed for the entire molecule. This term applies broadly to both elements and compounds, allowing for the calculation of quantities needed for reactions, conversions in stoichiometry, and understanding concentration in solutions. The use of molar mass in laboratory calculations underlines its significance in practical applications, ensuring accurate measurements in experiments and chemical processes.
