Element Chromium (Cr), Group 6, Atomic Number 24, d-block, Mass 51.996. One atomic mass unit is equal to 1.66 x 10-24 grams. ›› More information on molar mass and molecular weight. You should get a final result of 51.996. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. Atomic mass of Chromium is 51.9961 u. In other words, in every 100 chlorine atoms, 75 atoms have a mass number of 35, and 25 atoms have a mass number of 37. To calculate the relative atomic mass, A r , of chlorine: Enter a chemical formula: Browse the list of common chemical compounds. The unit of measure for mass is the atomic mass unit (amu). Naturally occurring chromium (24 Cr) is composed of four stable isotopes; 50 Cr, 52 Cr, 53 Cr, and 54 Cr with 52 Cr being the most abundant (83.789% natural abundance). Its atomic number is 24 and represented by the symbol Cr. Mass Percent: Chromium: Cr: 51.9961: 1: 100.000% ›› Calculate the molecular weight of a chemical compound.
