WebThe molecular mass (m) is the mass of a given molecule: it is usually measured in daltons (Da or u). Different molecules of the same compound may have different molecular … WebThe molar mass of a substance is the mass in grams of 1 mole of the substance. As shown in this video, we can obtain a substance's molar mass by summing the molar masses of its component atoms. We can then use the calculated molar mass to convert between mass and number of moles of the substance. Created by Sal Khan. craigard road

The atomic mass (ma or m) is the mass of an atom. Although the SI unit of mass is the kilogram (symbol: kg), atomic mass is often expressed in the non-SI unit dalton (symbol: Da) – equivalently, unified atomic mass unit (u). 1 Da is defined as 1⁄12 of the mass of a free carbon-12 atom at rest in its ground state. The protons and neutrons of the nucleus account for nearly all of the total mass of at… WebNH3 molecular weight. Molar mass of NH3 = 17.03052 g/mol. This compound is also known as Ammonia.
