Mole (unit) containing of hydrogen atoms in it, weighing exactly 1.008 grams (same as the Ar of one hydrogen atom). The molar mass of a substance is the mass of a sample divided by the amount of substance in that sample. This is a constant for any given substance. Since the unified atomic mass unit (symbol: u, or Da) is defined as 1/12 of the mass of the C atom, it follows that the molar mass of a substance, measured in grams per mole, is numerically equal to its mean atomic or molecular mass expressed in Da. One can determine the amount
Kavli Institute for the Physics and Mathematics of the Universe made of? What are its fundamental laws? Why do we exist?" The Institute for the Physics and Mathematics of the Universe was created in October 1, 2007, by its founding director Hitoshi Murayama and the University of Tokyo. It is funded by the Japanese Ministry of Science, as a part of their World Premier International Research Center Initiative. In 2012, the IPMU received an endowment from the Kavli Foundation and was renamed the Kavli Institute for the Physics and Mathematics of the Universe. Many notable scientists are employed at the IPMU. Among them: Kavli Institute for the Physics and Mathematics
