If it's your first encounter with chemistry, your instructor will want you to learn how to use theperiodic tableto find the atomic mass (atomic weight) of an element. This number usually is given below an element's symbol. Look for the decimal number, which is aweighted average of the ...
To find how much a certain number of atoms weigh in atomic mass units, multiply the atomic mass by the number of atoms. Note you will usually be doing this for very large numbers of atoms, and will need a calculator. Say you're given a problem to find the mass of 6.7 x 10^4 carb...
Each12C atom has six protons and six neutrons in its nucleus, adding up to an atomic mass of 12 AMU.Electronshave a low mass, so they are assumed to have a negligible effect. Consequently, the nucleus accounts for almost the entire mass of the atom of any element, which means that a ...
To calculate the average atomic mass of chlorine, use the information in a periodic table of the element (see Resources) to find the (weighted) average but changing the percents to decimals: (34.969×0.7577)+(36.966×0.2423)=35.45amu References Georgia State University Hyperphysics: Mass and W...

Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean. Leant how to find the mean here.
Atomic symbol:The atomic symbol (or element symbol) is an abbreviation chosen to represent an element ("C" for carbon, "H" for hydrogen and "O" for oxygen, etc.). These symbols are used internationally and are sometimes unexpected. For example, the symbol fortungstenis "W" because another...
