2. Microscale chemistry - Wikipedia

   en.wikipedia.org/wiki/Microscale_chemistry

   Microscale chemistry (often referred to as small-scale chemistry, in German: Chemie im Mikromaßstab) is an analytical method and also a teaching method widely used at school and at university levels, working with small quantities of chemical substances. While much of traditional chemistry teaching centers on multi-gramme preparations ...

   The reading scale can be enumerated such that the middle beam reads in 100 gram increments, the far beam can read from 0 to 10 grams, and the front beam can read in 10 gram increments. [4] The parts of a triple beam balance are identified as following: [5] Weighing pan - The area in which an object is placed in order to be weighed.

5. Molar mass - Wikipedia

   en.wikipedia.org/wiki/Molar_mass

   Obsolete terms for molar mass include gram atomic mass for the mass, in grams, of one mole of atoms of an element, and gram molecular mass for the mass, in grams, of one mole of molecules of a compound. The gram-atom is a former term for a mole of atoms, and gram-molecule for a mole of molecules. [7] Molecular weight (M.W.) (for molecular ...

   en.wikipedia.org/wiki/Mole_(unit)

   Before the 2019 revision of the SI, the mole was defined as the amount of substance of a system that contains as many elementary entities as there are atoms in 12 grams of carbon-12 (the most common isotope of carbon). [19] The term gram-molecule was formerly used to mean one mole of molecules, and gram-atom for one mole of atoms. [15]
