Possible quark mass formulae are discussed for an arbitrary number of quark flavors in a grand unified O(10) model, as well as in an ambidextrous model supplemented by additional discrete and/or global symmetries.doi:10.1016/0370-2693(79)91241-3T. Hagiwara...
the o terms are identical. No matter whether "formula mass" or "relative formula mass" is calculated all of the method steps and wer are the same.唔系应该 formula mass = mass number + mass number +... relative formula mass = relative atomic mass + relative atomic mass+...(...

Referring to the periodic table, the atomic mass of K is 39.10 amu, and so its molar mass is 39.10 g/mol. The given mass of K (4.7 g) is a bit more than one-tenth the molar mass (39.10 g), so a reasonable “ballpark” estimate of the number of moles would be slightly greater...

Density, mass per unit volume of a substance. The formula for density is d=M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of gram per cubic centimeter. For example, the density of water is 1 gram per cubic cen
