24.3, so its molar mass is 24.3 g.mol-1, and the molecular weight of CO 2 is 44.0, so its molar mass is 44.0 g.mol-1. Thus, molar mass allows us to quickly convert a mass into a number of moles or a number of moles into a mass. Chemists use this fact to quickly ... Retrieve Document
Atomic mass - Wikipedia
The atomic mass (m a) is the mass of an atom. One mole of a substance always contains almost exactly the standard atomic weight or molar mass of that hydrogen, which was taken as 1.00, and in the 1820s Prout's hypothesis stated that atomic masses of all elements would prove to be exact ...
