As a result of mitosis, each of your body cells

Mitosis is a process cell division, where one cell divides into two identical cells. Mitosis consists of four phases - prophase, metaphase, anaphase, telophase and cytokinesis.1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up.2. Metaphase: Chromosomes line up at the centre of the cell.3. Anaphase: The sister chromatides separate from each other to the oposite sides of the cells.4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
