WebbThe relative atomic mass of an element, symbol A r, is the relative mass of its atoms compared to the mass of a carbon-12 atom. The A r values for elements are given in the periodic table. WebbThe total number of nucleons is the mass number, A. These numbers are related by. A = Z + N. 10.1. A nucleus is represented symbolically by. Z A X, 10.2. where X represents the chemical element, A is the mass number, and Z is the atomic number. For example, 6 12 C represents the carbon nucleus with six protons and six neutrons (or 12 nucleons). Webb15 sep. 2024 · The formula mass of FeCl 3 is 162.19 amu. When we distribute the subscript 3 through the parentheses containing the formula for the ammonium ion, we see that we have 3 nitrogen atoms and 12 hydrogen atoms. Thus, we set up the sum as follows: The formula mass for (NH 4) 3 PO 4 is 149.12 amu. Exercise 3.5. 1 in utero wallpaper
