The atomic masses of some common elements are given in Table 7.1. The unit of atomic or molecular mass in this table can be either g/gmol, kg/kmol, lbm/lbmol, etc. In addition, the number of mols n of a substance with mass m and molecular (or atomic) mass M is given by Eq. (...
Because of the distribution of chain sizes it is common to use moments of the distribution to specify the molar mass of a resin. For example, the number average molar mass, Mn, is the total mass of polymer divided by the number of polymeric chains (i.e., the average molecular weight)....
Through knowing the mass and molar mass of a compound, one can then determine the number of a moles in a specific compound. Each substance possesses a unique molar mass because the atoms of various elements contain different numbers of protons, neutrons, and electrons, therefore they each have...

The Pleistocene presence of the genus Homo in continental Southeast Asia is primarily evidenced by a sparse stone tool record and rare human remains. Here we report a Middle Pleistocene hominin specimen from Laos, with the discovery of a molar from the T
such as the expected proportion ofM2/M1when the third molar is absent. Furthermore, we found that some variability in third molar size could not be explained by the influence of the inhibitory cascade. Overall, we found considerable clade-specific differences in relative molar sizes among anthropo...
which include some of the largest known Mesozoic mammals40,41. Body mass inPriacodoncan be estimated by reference to regressions based on dentary length42, estimated skull length43, and postcranial elements2,44. These estimates range from 40.9–60.6 g inP.fruitaensis, to 111–175 g inP.fero...
The Curie temperature of pure magnetite occurs at 580 °C ± 2 °C [397]. Substitution of FeII and/or FeIII by Al3+, Cr3+, Ti4+, Mg2+, Ni2+, Ca2+, Mn2+, and other ions which are common in natural magnetites, lowers the Curie temperature from 580 °C for 100 mass % Fe3O4...
where χi is the mole fraction, wi is the mass (or weight) fraction, Mi is the molecular mass of chemical species i in the mixture, Mm is the equivalent molecular mass of the mixture, and pm is the total pressure of the mixture. Example 15.12 Calculate the entropy produced per mole of...
