For example, the atomic weight of the element chlorine is 35.453, determined by averaging the atomic masses and relative abundances of its two main naturally occurring isotopes, which have atomic masses of about 35 and 37.
The percent composition (percentage composition) of a compound is a relative measure of the mass (or weight) of each different element present in the compound. % by mass of oxygen + % by mass of hydrogen = 100 % (% by mass of water molecule).For any element present in any molecule:And, if you add together the % by mass of every element present in the compound the result will be 100%. a Y b Z c :Calculate the percent by mass (weight) of sodium (Na) and chlorine (Cl) in sodium chloride (NaCl). Calculate the percent by mass (weight) of each element present in sodium sulfate (Na 2 SO 4). by mass of oxygen + % by mass of hydrogen = 100 % (% by mass of water molecule). For any element present in any molecule: And, if you add together the % by mass of every element present in the compound the result will be 100%. a Y b Z c :
