How are atomic masses determined
WebThe atomic mass of an element is the weighted average of the atomic masses of the naturally occurring isotopes of that element. The average atomic masses are the values we see on the periodic table. 0.7577 (34.969)+ 0.2423 (36.966)= 35.453 The weighted average is determined by multiplying the percent of natural abundance by the actual mass of ... WebStep 1: Define atomic mass Each element has its own atomic mass. The unit of atomic mass is u (unified mass) Step 2: The atomic mass of water The formula for water is H 2 O. The atomic mass of water is 18. 01 u. Step 3: Calculation of atomic mass of water

WebThe unit of atomic mass was thereby defined as 1/16 the mass of an oxygen atom. In 1929 it was discovered that natural oxygen contains small amounts of two isotopes slightly heavier than the most abundant one and that the number 16 represented a weighted average of the three isotopic forms of oxygen as they occur in nature.
